Rain-catching tubes provide new hydropower source for tropical regionsAn experiment in Singapore showed that charge separation could be established by rainwater flowing through narrow tubes. The separation, which creates a voltage, could be scaled up in regions of high rainfall to provide a clean energy source. Science NewsAmong renewable sources, geothermal rivals hydropower in lifetime costAs of 2024, the levelized cost of energy—the average cost per unit of energy over the lifetime of a power plant—for geothermal power is surpassed only by solar photovoltaic and onshore wind. Geothermal's LCOE has remained relatively unchanged since 2007, with significant decreases held back by significant upfront installation costs. Our World in DataNational Lab creates tools and apps to enable hydropower development across the USA collection of visual resources helping researchers assess available hydropower opportunities across the US. Oak Ridge National LaboratoryAn explaination of the value of pumped storage hydropowerA new US Department of Energy-sponsored guidebook helps illustrate the value of investing in the world’s best clean energy storage technology. TED-EdWhy is hydropower important when other power sources go dark?Hydropower can ramp up, recoup shortfalls, and stabilize the grid nearly instantaneously. A new study quantifies the energy source’s contribution to grid stability. Pacific Northwest National LaboratoryAn overview of hydropowerHydropower, or the use of the natural flow of moving water to generate electricity, is one of the oldest and largest sources of renewable energy. U.S. Department of EnergyHydropower 101Hydropower—energy created from fresh, moving water—is the world's oldest form of renewable energy. National Renewable Energy LaboratoryNiagara Falls is New York State’s biggest electricity producerThe Robert Moses Niagara Power Plant and Lewiston Pump-Generating Plant together produce up to 2.6 million kilowatts—providing about 20% of New York State’s hydropower and supplying electricity to over 3 million homes. NY Power AuthorityClean energy technologies are more mineral-intensive than burning fossil fuelsSolar panels use silver due to its high conductivity, hydropower plants use chromium in their steel alloys, and geothermal plants need titanium to withstand abundant heat and pressure. Lithium—used in energy storage—is expected to see over 500% increased demand from 2020 to 2025. Visual CapitalistThere's a bitcoin mine in remote ZambiaIn Zambia, a small hydropower plant draws water to power a town of 15,000 people—and a bitcoin mine. A shipping container containing 120 computers mining bitcoin—solving complex calculations to win the reward of several bitcoin—was set up near the plant to use its cheap electricity, and share its revenue.
