WHO Wants Sentinel Surveillance Influenza Implemented in Hospitals

first_imgParticipants of the Training in a group photo The World Health Organization (WHO) has embarked on the implementation of the Sentinel Surveillance for Influenza in various hospitals, to reduce the death rate at the result of  wrongful treatment.WHO said influenza is estimated to be at 3-5 million cases of severe illness and 250,000 to 500,000 deaths worldwide.According to WHO, currently there are limited data regarding epidemiological patterns, risk factors and burden of influenza diseases as well as the economic impact in tropical and subtropical regions in Africa.WHO disclosed its plan yesterday at the opening of a five-day training workshop, which brought together over 50 health workers from east, west and central Africa. The program was held in Monrovia under the theme, “Implementation of Sentinel Surveillance Influenza in Liberia.”Mosoka Fallah, National Public Health Institute Deputy Director General for Technical Services, disclosed that all the health centers in Liberia present about 4.3 million people with fever yearly,  but truly speaking there are only 2.2 million people diagnosed with real  malaria.Fallah said the remaining 2.1 million, who are not diagnosed with malaria, still receive anti malaria treatment and antibiotics.“This is almost like shooting a brown bullet, knowing the judicious use of antibiotic. Imagine what will happen when they are treating 2.1 million people with anti-malaria drugs and antibiotic for diseases they do not know,” he said.Fallah urged health workers to make use of the knowledge they will learn from the training in hospitals and labs, indicating that “knowledge is useless if you cannot apply it.”Also speaking was Professor Richard Njouom, a facilitator at the training exercise. He said the objective of the training is to identify the gaps in the sentinel surveillance for influenza not only in Africa but globally, which would help to strengthen the detection diagnosis and monitoring factors in Africa.Prof. Njouom said the aim of the training is to enable participants describe the virology and epidemiology of the influenza virus and to develop a work-plan for implementation of sentinel surveillance for influenza.“We also want to describe respiratory specimen collection and handling transportation as well as to process, organize, summarize and present the sentinel for influenza,” he said.Nuha Mahnound, who is from WHO Liberia, told participants to be the front soldiers in the implementation of Sentinel Surveillance Influenza to make it a success story in Liberia.In 2011, the World Health Organization (WHO) funded the Strengthening Influenza Sentinel Surveillance in Africa (SISA) project with the goal of developing and strengthening influenza surveillance in eight countries in sub-Saharan Africa, including Sierra Leone. The process was described as establishing a functional Influenza Sentinel Surveillance (ISS) system in Sierra Leone, a post-conflict resource-poor country previously lacking an influenza monitoring system.Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window)last_img read more

Cahill named new Chelsea captain

first_imgBut Chelsea boss Antonio Conte has now confirmed that the England international will be captain on a permanent basis, albeit he wants the club’s other experienced players to also show their leadership qualities.“I think that it’s right to continue with Cahill. If he plays, it’s right he’s the captain,” said Conte.“Why? Because he stayed in Chelsea for many years and played a lot of games and showed good characteristics to be this.“I think also we can have other captains in our team, could be [Cesar] Azpilicueta, [David] Luiz, and also, in the future, it could be Thibaut Courtois, Cesc Fabregas.“I think every single player must improve in this and understand [they have] to take more responsibility because we lost big players and we need now to find these new players to create this fundamental for Chelsea. It is very important for our future success to create this base.“But I think right now it’s right to give the armband to Gary. He’s playing with the club for many years, he has the right characteristic to be a good captain.”0Shares0000(Visited 1 times, 1 visits today) 0Shares0000Chelsea’s defender Gary Cahill celebrates scoring against Everton on April 30, 2017LONDON, United Kingdom, Jul 24- Gary Cahill has been named as Chelsea’s new permanent captain after the departure of long-time skipper John Terry.Cahill wore the armband for much of last season after fellow centre-half Terry was largely restricted to a substitute’s role.last_img read more

Leicester 3-1 Everton: Vardy makes a scoring return as champions put on a show

first_imgThe party was well underway in Leicester, but the newly-crowned Premier League champions showed no hangover as they beat Everton 3-1 at the King Power.Leading marksman Jamie Vardy made a goalscoring return after a two-game suspension, beating Joel Robles after just five minutes. Claudio Ranieri has been hailed the new King in East Midlands, but it was midfielder Andy King who increased the volume in the stadium after 33 minutes when he lashed home with a royal finish inside the box. Vardy did well to beat the offside trap on 65 minutes and he was brought down in the box by Matthew Pennington. The England forward stepped up to coolly fire past Robles – his 26th goal for club and country this season – to send the Foxes even further in dreamland. The home side were awarded another penalty soon after but Vardy opted for power, sending the ball flying into the stands. Leicester fans cheered ironically as Everton pulled one back in the closing stages of the game, Kevin Mirallas finishing well under Kasper Schmeichel.Leicester were professional as ever as they put on a show before collecting the Barclays Premier League trophy. The Foxes have captured the imaginations of football fans across the globe as they have regularly put on a show, going from 5000/1 outsiders to confirmed champions. But it was Ranieri’s compatriot and legendary tenor Andrea Bocelli who stole the show before kick-off, revealing a Leicester City kit as he lifted the roof infront of a capacity crowd. And the historic team were soon welcomed onto the field with a guard of honour formed by the out-of-form Everton. The title party started at Jamie Vardy’s house on Monday as Tottenham dropped points at Chelsea, and Vardy showed no let up when he met King’s cross in the box, converting with a first-time volley from six yards. Assist-maker King, who joined Leicester in 2006, has won League One, the Championship and now the Premier League with the Foxes. And he capped a fine week of celebrations by meeting the ball in the box, smashing it powerfully past Robles and into the back of the net. PFA Player of the Year Riyad Mahrez was desperate to get on the score sheet after a fantastic season in the East Midlands. He tried to get the ball onto his left foot to curl a shot in the far corner and minutes later he failed to convert a free-kick from a deadly position. Everton were dreadful with some fans suggesting they WANT Roberto Martinez to get the sack from Goodison.Young defender Pennington, who escaped a red card for a last-man challenge on Mahrez in the first half, fouled Vardy in the box after the former non-league striker broke through. The ex-Fleetwood man stepped up to convert past Robles and the celebrations in the King Power continued. Vardy had the chance to catch Harry Kane in the scoring charts when Darron Gibson brought down Jeffrey Schlupp. The 29-year-old stepped up to take the resulting penalty, this time putting his foot through the ball and sending it flying over the crossbar. His first senior hat-trick would have to wait. Mirallas’ goal late on did not dampen spirits, except Schmeichel’s, who was furious not to get the clean sheet. 1 Jamie Vardy doubles his tally – his 26th of the season for club and country last_img read more

1974 World Cup saw the first ever Red Card

first_imgThe 1974 FIFA World Cup, the tenth staging of the World Cup, was held in West Germany.Some of football’s most successful nations did not qualify, including 1966 champions England, France, hosts of the 1970 tournament Mexico, Spain, 1966 third-place finishers Portugal, Belgium, Czechoslovakia, Hungary and Romania.16 teams qualified, divided into four groups of four. Each played a round-robin with two points for a win and one for a draw, and goal difference used to separate teams level on points. The top two teams from each group advanced to the next stage.However, in a change from the format used in the previous five competitions, the second round consisted of another group stage: the eight remaining teams were divided into two groups of four. The winners of each group played each other in the final, and the second place teams in each group played each other in the third/fourth place match.Johan Neeskens scoring after only two minutes in the finalThe tournament was held mostly in bad weather, and the stadia had few protected places. Few western European nations had qualified, of which only The Netherlands, West Germany and Sweden made it past the Group Stage. Fans from the Eastern neighbour states were hindered by political circumstances.Carlos Caszely of Chile became the first player to be sent off with a red card in a World Cup match, during their match against West Germany. Red cards were formally introduced in World Cup play in 1970, but no players were sent off in that tournament.Two teams made a particularly powerful impact on the first round. The Netherlands demonstrated the “Total football” techniques pioneered by the top Dutch club Ajax, in which specialised positions were virtually abolished for the outfield players, and individual players became defenders, midfielders or strikers as the situation required. The Dutch marked their first World Cup finals since 1938 by topping their first-round group, with wins over Uruguay and Bulgaria and a draw with Sweden. Sweden joined the Dutch in the second group round after beating Uruguay 3–0.Poland, meanwhile, took maximum points from a group containing two of the favourites for the tournament. They beat Argentina 3–2, trounced Haiti 7–0, then beat Italy 2–1 – a result that knocked the Italians out of the Cup and resulted in Argentina sneaking to the second group round on goal difference. While Haiti didn’t do particularly well in their first World Cup finals (losing all three of their games and finishing second to last ) they did have one moment of glory. In their opening game against Italy, they managed to take the lead with a goal from Emmanuel Sanon, before eventually losing 3–1 (Italy had not conceded a goal in 12 international matches). That goal proved to be a significant goal as it ended Dino Zoff’s run of 1142 minutes without conceding a goal.Group 2 was a particularly close group. With Brazil, Yugoslavia and Scotland drawing all their games against each other, it was decided by the number of goals these three teams scored when defeating Zaire. Yugoslavia hammered the African nation 9–0, equalling a finals record for the largest margin of victory. Brazil beat them 3–0. Scotland however only managed a 2–0 margin, and so were edged out of the tournament on goal difference. They were the only team that did not lose a game in the tournament as well as becoming the first ever country to be eliminated from a World Cup Finals without having lost a match.Gerd Muller (extreme right) scores the winning goal in the 1974 finalGroup 1 contained both East Germany and the host West Germany , and they both progressed at the expense of Chile and newcomers Australia. The last game played in Group 1 was also the most anticipated, a big clash between the two German teams. West Germany was already assured of progression to the second round whatever the result. In one of the most politically charged matches of all time, it was the East that won, thanks to a late Jurgen Sparwasser goal. This embarrassing result forced a realignment of the West German team that would later help them win the Cup.Second round.Coincidentally, the two second-round groups both produced matches that were, in effect, semi-finals. In Group A, the Netherlands and Brazil met after each had taken maximum points from their previous two matches. In Group B, the same happened with West Germany and Poland – so the winners of these two games would contest the final.In Group A, two goals from the inspirational Johan Cruyff helped the Dutch side thrash Argentina 4–0. At the same time, Brazil defeated East Germany 1–0. The Dutch triumphed over East Germany 2–0 while in the “Battle of the South Americans”, Brazil managed to defeat Argentina 2–1 in a scrappy match. Argentina and East Germany drew 1–1 and were on their way home while the crucial match between the Netherlands and Brazil turned into another triumph for ‘total football’, as second-half goals from Johan Neeskens and Cruyff put the Netherlands in the final. However the match would also be remembered for harsh defending on both sides.Meanwhile, in Group B, West Germany and Poland both managed to beat Yugoslavia and Sweden. The crucial game between the Germans and the Poles was goalless until the 76th minute, when Gerd Muller scored to send the hosts through 1–0. The Poles took third place after defeating Brazil 1–0.Final.The final was held on 7 July 1974 at Olympiastadion, Munich. West Germany was led by Franz Beckenbauer, while the Dutch had their star Johan Cruyff, and their Total Football system which had dazzled the competition. With just a minute gone on the clock, following a solo run, Cruyff was brought down by Uli Hoenes close to the German penalty area, and the Dutch took the lead from the ensuing penalty by Johan Neeskens before any German player had even touched the ball. West Germany struggled to recover, and in the 26th minute were awarded a penalty, after Bernd Holzenbein fell within the Dutch area, causing English referee Jack Taylor to award another controversial penalty. Paul Breitner spontaneously decided to kick, and scored. These two penalties were the first in a World Cup final. West Germany now pushed, and in the 43rd minute, in his typical style, Gerd Muller scored what turned out to be the winning goal, and the last of his career as he retired from the national team. The second half saw chances for both sides, with Müller putting the ball in the net for a goal that was disallowed as offside. In the 85th, Hölzenbein was fouled again, but no penalty this time. Eventually, West Germany, European Champions of 1972, also won the 1974 World Cup.West Germany captain Franz Beckenbauer lifts the 1974 World Cup trophyThis was the only case of the reigning European champions winning the World Cup, until Spain (champions of the UEFA Euro 2008) defeated the Netherlands in the South Africa 2010 FIfA World Cup Final. France have also held both trophies, albeit in a different order, at the same time by winning the 1998 World Cup followed by Euro 2000.Joao Havelange former FIFA President from 1974 to 1998) claimed that the 1966 and 1974 World Cups were fixed so that England and Germany would win respectively.This was only the second time that a team had won the World Cup after losing a match in the Finals (West Germany losing to East Germany during the group stage). The previous occasion was West Germany’s earlier win in 1954.Poland’s Grzegorz Lato led the tournament in scoring seven goals. Gerd Muller’s goal in the final was the 14th in his career of two World Cups, beating Just Fontaine’s record of 13, in his single World Cup. Müller’s record was only surpassed 32 years later, in 2006 by Ronaldo’s 15 goals from three World Cups and then 8 years after, in 2014 by Klose’s 16 goals from four World Cups.Grzegorz Lato of Poland won the golden boot with seven goalsGunter Netzer who came on as a substitute for West Germany during the defeat by the East Germans, was playing for Real Madrid at the time: this was the first time that a World Cup winner had played for a club outside his home country.This is the last of four FIFA World Cup tournaments to date with no extra-time matches. The others are the 1930, 1950, and 1962 tournaments.Commentslast_img read more

How slow can you go?

first_imgThere is no first class on these planes.Nor movies, nor champagne – not even budget economy class with a glass of water!For these are the planes that will take you to the wilds of Alaska where jumbos fear to tread and where there are no runways – just the occasional sand bars on the side of a streams or just small patch of grass.All the pilots of these planes need to land is an 18mtr clearing not the 3000mtrs of concrete that an A380 super jumbo requires.For that was the winning distance at the 2013 annual fly-in at Valdez Alaska where pilots of these Short take-off and Landing (STOL) planes fight it out to land on a dime.The two-day competition pits the flying skills of bush pilots to see not who can fly the fastest but who can fly the slowest!And not only is there a large crowd watching the dare devils but black bears and Dall sheep watch on the surrounding hills.The pilots are often veterans of their craft with more than 25,000 hours of flying in remote Alaska.And the best planes are typically heavily modified.According to Wired.com there are four categories for competitors at the Valdez fly-in.The light touring, heavy touring and stock bush classes all feature production-certified planes.While modifications can be made they must be approved for use on production planes.However on the alternate bush category anything goes but the changes must be built under the US regulator’s experimental category.Or pilots can build a design from the ground up.last_img read more

How to Make Hydropower More Environmentally Friendly

first_imgBy MATT WEISERHumanity got its first large-scale electricity thanks to hydropower. On August 26, 1895, water flowing over Niagara Falls was diverted to spin two generators, producing electricity to manufacture aluminum and carborundum. Since then, millions of dams have been built worldwide, transforming the energy of moving water into the energy of moving electrons. When we need it, the water spins magnets past a coil of copper wire to give us heat, light, and entertainment.The basics of hydropower haven’t changed much in 120 years. But now scientists and engineers are taking a fresh look at hydropower to try to make it more environmentally friendly.That’s because, while hydro provides 85% of the world’s renewable electricity, it comes with a cost. Along with more commonly known issues such as habitat disruption, recent studies suggest reservoirs created by hydroelectric dams are a significant source of greenhouse gas emissions. Looking holisticallyThe Penobscot is a rare case in which the concept of “basin planning” has been applied to hydropower reform. Rather than focus on improving a single dam, basin planning examines all the dams in a river basin or watershed to find solutions at the ecosystem scale. The goal is to reduce a project’s environmental footprint while maximizing energy and water resources.While basin planning has been applied successfully to new hydropower development — notably by the Tennessee Valley Authority in the 1930s — its application to contemporary biodiversity and sustainability challenges is still rare. Another example in Tanzania involved a basinwide approach to reallocating water from the Pangani River, which has seen flows decline due to climate change.Such efforts are challenging, because multiple dams in the same basin often have different owners and even different functions, and their licensing and regulation occur on separate timetables.A proposal in California is approaching basinwide water challenges differently. The $4.4 billion Sites Reservoir is an “off-stream” project, meaning it would not dam a river but would store water pumped into an arid valley from the Sacramento River, then generate electricity when the water is released.But making electricity is not the primary focus. Jim Watson, general manager of the Sites Joint Powers Authority, said the reservoir would be filled during flood events, when the Sacramento River has surplus water. It would then be released to satisfy water quality rules or provide fishery flows when existing reservoirs in the Sacramento basin don’t have enough water, and the water would then flow to buyers downstream. Those existing reservoirs, owned by the state and federal governments, are increasingly challenged to meet environmental requirements amid growing water demand and emerging effects of climate change.“We’re really looking at how to create this flexible operation that can adjust to different priorities over time,” Watson says. “So as we see the effects of climate change, we can reprioritize how the water is put to use and adjust the timing of that water.”In short, Sites is a new reservoir with environmental benefits as a primary objective. That’s a shift in focus that may become a lot more common in the hydropower world. Matt Weiser is a journalist based in Washington, D.C. This post originally appeared at the website Ensia. For Storing Electricity, Utilities Turn to Pumped HydroUndamming Rivers Could Make Roof for PVPumped Hydro Power Storage RELATED ARTICLES Fixing existing problemsMany environmental groups and local communities are focused on existing dams’ problems.Restoring fish passage is a major focus. Many large dams were built without fish ladders and remain an absolute barrier to fish migration. Climate change makes this an even greater concern, because migratory species like salmon and steelhead need access to cold-water spawning habitat above dams as temperatures warm.But adding fish ladders often exceeds the original construction cost of some large dams. So compromises include trap-and-haul programs, in which fish are collected and transported by tanker truck around dams, and motorized lifts in various configurations. The most unusual form is an experimental “salmon cannon” — developed with DOE support — that can shoot adult salmon over a dam through a tube.Reforming the timing and intensity of water releases is another major focus. Natural systems evolved with highly variable river flows caused by storms, not the consistent, low-intensity water releases characteristic of hydropower generation. For example, short periods of high-velocity water releases have been conducted at Glen Canyon Dam on the Colorado River to mobilize accumulated sediment in the river channel, helping restore riparian habitat. Such variable flows also please those who like river recreation, such as rafters and kayakers.Research is also under way to minimize greenhouse gas emissions from reservoirs. Reservoirs may emit substantial amounts of methane, a powerful greenhouse gas, when vegetation and algae decay with changing water levels. Solutions may include controlling erosion in upstream watersheds and managing water elevation more carefully, especially during warm seasons.center_img Removing trapped pollutantsReservoirs also trap pollutants left behind by past industrial practices, which flow downstream and concentrate behind dams. These chemicals can accumulate in fish, making them dangerous for people and wildlife, and pose a health hazard in drinking water.Removing pollutants trapped in a reservoir presents a huge logistical challenge.One solution has emerged at Mirror Lake in Dover, Delaware. The lake, originally a natural water body, was modified years ago by constructing a small weir to control the water elevation. Its sediments are contaminated by legacy industrial waste, including PCBs, dioxins, pesticides and mercury. A longstanding advisory warns against consuming fish from the lake — a condition common to thousands of reservoirs worldwide.Upal Ghosh, professor of chemical engineering at the University of Maryland, Baltimore County, developed a method to deal with such waste using SediMite, a product that mixes activated carbon with clay or sand into pellet form. The pellets are dispersed on the water surface and then sink to form a layer on the lake bed that absorbs and caps the contaminants.The Delaware Department of Natural Resources and Environmental Control tried the treatment at Mirror Lake in 2013. The $1 million project dispersed 79 tons (72 metric tons) of the activated carbon material over the lake surface — the first real-world application of the method.Tests after one year showed a 70 percent reduction of PCB levels in the water, says Rick Greene, an environmental engineer with the state. They also showed a 60 percent decline of PCBs in fish tissue, a change previously expected to take 25 years if the lake had been left to flush out on its own.The researchers recently took samples to assess the lake after three years. Greene hopes that the results will allow the state to lift its fish consumption advisory, giving people access to this local food supply again — something previously expected to take 50 more years.“That’s just a long time, and it’s downright depressing when you think about it,” Greene says. “We see this as a major game changer for improving not only water quality but also fish health.” Coming up for reviewAltering reservoir functions is difficult because many dams are locked into very long regulatory licensing terms — as long as 50 years in the United States. Many also have flood protection as a primary function, so water storage levels and release practices are governed by rigid safety rules.Only now are many of America’s largest hydroelectric reservoirs coming due for new licenses, a process overseen by the Federal Energy Regulatory Commission. In many cases, this represents the first time that many large dams have been completely re-examined in the context of contemporary environmental laws, like the Endangered Species Act and Clean Water Act.Among other requirements, FERC can order dam owners to release more water for habitat and recreation, and require fish passage facilities on dams that have never had them. It can even order a dam to be removed. However, it has not yet tackled the problem of greenhouse gas emissions in any relicensing effort.The Penobscot River in Maine illustrates the potential. Numerous hydroelectric dams on the river, under different owners, came due for relicensing in the late 1990s and early 2000s. In the middle of that process, in 1999, they were consolidated under a single owner, PPL Maine.This was a convenient result of energy-industry deregulation by the U.S. government, which made it more attractive for some companies to buy and sell hydropower assets, says Andy Goode, vice president of U.S. programs at the Atlantic Salmon Federation.Goode helped lead an effort by a number of organizations to work with PPL Maine to reform operation of all its Penobscot dams. The conditions they negotiated became part of a new 50-year operating license issued by FERC.As part of a project known as the Penobscot River Restoration Trust two functioning hydroelectric dams were removed on the Penobscot River in Maine resulting in the return of fish species such as river herring, American shad and Atlantic salmon — while not reducing total hydroelectric output. (Photo: U.S. Fish and Wildlife Service Northeast Region)The project became known as the Penobscot River Restoration Trust. It wrapped up in 2016 after more than a decade of work, resulting in improved fishery flows, removal of two functioning hydroelectric dams and decommissioning of a third. Those dams were purchased and decommissioned by a coalition of environmental groups, which raised $25 million for the effort.“We pretty much took a look at every dam on the river and figured out how we might be able to incorporate that dam into an overall solution,” Goode says.The project has already seen results: Three fish species have returned in numbers not seen in decades — including river herring, American shad, and Atlantic salmon — and improvements in several other species are anticipated. And this was achieved without reducing total hydroelectric output because two remaining dams got additional generation capacity and a mothballed plant was put back in operation. Thousands of new projects are plannedMeanwhile, a 2015 study in the journal Aquatic Sciences estimated that at least 3,700 major new hydroelectric dams are proposed or under construction worldwide, most in developing countries.As a result of this surge in hydro development, an international coalition of governments, utilities and non-governmental organizations launched the Hydropower Sustainability Assessment Protocol in 2011. These voluntary standards were created as a road map to make new hydropower more environmentally benign and less harmful to local communities, which are often displaced or compromised by large projects.It remains to be seen how effective this effort has been. More than 60 other NGOs have criticized the protocol, saying it is not rigid enough to ensure that sustainability goals are met and ignores a number of concerns, including ones related to human rights and the risk that dams could set off earthquakes.Indeed, many environmental groups would prefer to see no new dams built. They argue that other sustainable energy sources have evolved as better alternatives.“Wind and solar have become cheaper in many countries, they are less risky in climate terms, they can be deployed more quickly, and they have smaller environmental and social footprints,” says Kate Horner, executive director of International Rivers, an environmental group based in Berkeley, California.Others, though, do see a place for hydro, despite its impacts. “I just don’t think, when you put a giant chunk of concrete in the middle of a river, that there’s any way to make that environmentally benign,” says Kelly Catlett, western states director at the Hydropower Reform Coalition. “I do think there is a point at which a dam is providing so many societal benefits that that does outweigh the environmental impacts it’s causing.”One way to make dams more sustainable is to not build new ones, but instead modify non-powered dams, like the Opekiska Lock and Dam in West Virginia, to generate electricity.

Maintaining healthy natural stream functions is a primary objective of this effort to ensure that the expansion of hydropower does not expand its harmful impacts, also.At the same time, the department is developing new environmental metrics to assess the environmental performance of new hydropower. The peer-reviewed process starts with defining what sustainability means for hydropower, then setting performance measures for different environmental effects, such as fish migration, energy efficiency and greenhouse gas emissions.Battey says that a major share of the growth will come by adding generation to existing unpowered dams and other structures, like irrigation canals, navigational locks, and even pipelines. There are about 2,200 dams in the U.S. producing hydropower, and about 85,000 that don’t. Of these, the DOE estimates that about 1,800 could be modified to generate electricity. The U.S. Department of Energy is among those working to make hydropower better for the environment.“Not only DOE, but really the entire hydro industry has agreed that more work needs to be done,” says Hoyt Battey, manager of market acceleration and deployment for the agency’s Wind and Water Power Technologies Office. “Hydro is going to continue to grow and has a lot of future opportunity that most people just aren’t aware of.”Current global hydropower production is estimated at 1,700 gigawatts, providing about 2% of total electric generating capacity.In the U.S. — where in 2014 hydropower provided a little more than 6% of total electricity generation and made up about 48% of renewable generation, according to the DOE — hydropower capacity grew by 1.5 GW in the decade prior to 2015, reaching a total of 100 GW, according to the Energy Information Administration. (Wind, solar, and natural gas capacity grew faster, while coal and oil declined and nuclear was essentially flat.)In a Hydropower Vision report released in July 2016, the DOE estimates U.S. hydropower could grow a surprising 50% by 2050.last_img read more
