Factsheet: Hydropower and ecology
Accounting for 20% (around 3,400 TWh) of global electricity production – even though its contribution to gross final energy consumption is only about 2% – hydropower plays a vital role. This is largely due to the fact that it can be readily regulated to meet fluctuations in demand and substantial reserves can be stored in reservoirs. Hydropower supplies around 56% of Switzerland's ...

Long-term variations in the net inflow record for Lake Malawi
Lake Malawi is the third largest lake in Africa and plays an important role in water supply, hydropower generation, agriculture and fisheries in the region. Lake level observations started in the 1890s and anecdotal evidence of variations dates back to the early 1800s. A chronology of lake level and outflow variations is presented together with updated estimates for the net inflow to the ...

Data Highlight: Hydropower Continues Steady Growth
World hydroelectric power generation has risen steadily by an average 3 percent annually since 1965. In 2011, at 3,500 billion kilowatt-hours, hydroelectricity accounted for roughly 16 percent of global electricity generation, almost all produced by the world’s 45,000-plus large dams. Graph on World Hydroelectric Generation, 1965-2011 Four countries dominate the hydropower landscape: ...

Energy recovery potential using micro hydropower in water supply networks in the UK and Ireland
The supply and treatment of water is a highly energy intensive process, resulting in large amounts of greenhouse gas emissions as well as incurring large economic costs. Both governments and water service providers worldwide recognise the need for more sustainable water supply systems. In recent years, the use of hydropower turbines within water supply networks has been shown as a viable option ...

Getting to 100% Renewable: Dream or Reality?
Attending the Future of Energy Summit last month, an annual event hosted by Bloomberg New Energy Finance, I was struck – for the second year running – by the rapid pace of cost reductions and innovation happening across the clean energy spectrum. With the news that a recent solar photovoltaics tender in Dubai obtained bids at less than US6c/kWh, to major investments in electricity ...

Control systems for small hydropower plants: a review
Hydropower is emerging as a major contributor to world energy requirement. It is inexhaustible, clean and has many other benefits like flood mitigation, water supply, irrigation, etc. However, large-scale hydropower generation suffers from inherent disadvantages, such as massive financial outlays, long gestation periods, geological surprises, environmental factors and rehabilitation of the ...

Optimizing multi-reservoir operation rules: an improved HBMO approach
We present an improved version of Honey Bees Mating Optimization (HBMO) algorithm to develop operating rules for multi-reservoir systems. The performance of the proposed model is tested through sensitivity analysis and comparing the result with those of a real-coded Genetic Algorithm (GA) for a 60-month period single-reservoir operation problem. The improved model is subsequently employed to ...

Water sustainability decision-making for electric utilities case study
The electric power generation sector uses approximately 41% of all freshwater withdrawn in the United States—more than any other water use sector. The Electric Power Research Institute (EPRI) conducts research and development to help address challenges in electricity generation, delivery, and use, including water sustainability issues. On behalf of EPRI, LimnoTech conducted research and is ...

Asia-Pacific Analysis: Go green not nuclear
Crispin Maslog says the region should follow the Philippines' lead and focus on renewable, not nuclear power. A year after the Fukushima nuclear disaster, questions remain over the role of nuclear power in the developing world, including South-East Asia and the Pacific. Nuclear power had a renaissance, driven by rapidly growing energy demands, and fading memories of high-profile disasters at ...
