Shifting winds in turbine arrays
Researchers modeling how changes in air flow patterns affect wind turbines' output power have found that the wind can supply energy from an unexpected direction: below.
Urgent investment required for battery storage of green electricity
In the coming years, the Netherlands will have to work hard on Smart Grids, intelligent local networks with new storage capacity for green electricity. It will thus be possible to counter the impending instability ...
Intermittence of wind energy hardly affects CO2 emissions in Spain
Researchers at the UPM have found that real contribution to emissions targets is positive even in energy markets with high penetration of wind energy.
Turning plastic bags into high-tech materials
University of Adelaide researchers have developed a process for turning waste plastic bags into a high-tech nanomaterial.
NREL calculates emissions and costs of power plant cycling necessary for increased wind and solar
New research from the Energy Department's National Renewable Energy Laboratory (NREL) quantifies the potential impacts of increasing wind and solar power generation on the operators of fossil-fueled power plants in the West. ...
Highly active catalysts could be key to improved energy storage in fuel cells and advanced batteries
MIT researchers have found a new family of materials that provides the best-ever performance in a reaction called oxygen evolution, a key requirement for energy storage and delivery systems such as advanced ...
Study: Wind farms killed 67 eagles in five years
A new study by government scientists says wind energy facilities have killed at least 67 golden and bald eagles in the last five years, but the number could be much higher.
Scientists calculate the energy required to store wind and solar power on the grid
Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in ...
NREL study suggests cost gap for Western renewables could narrow by 2025
A new Energy Department study conducted by the National Renewable Energy Laboratory (NREL) indicates that by 2025 wind and solar power electricity generation could become cost-competitive without federal subsidies, if new ...
German energy giants pull plug on conventional power
German power company RWE is shutting six domestic plants and rival E.ON is threatening to relocate to Turkey as the sector tots up the cost of the government's energy policy turnaround.
Team succeeded in precisely measuring expansion velocity of shockwave of supernova remnant W44
A research team led by Tomoro Sashida and Tomoharu Oka (Keio University) has succeeded in precisely measuring the expansion velocity of a shockwave of the supernova remnant W44. The remnant is located in ...
Localized wind power blowing more near homes, farms and factories
Americans are increasingly installing wind turbines near their homes, farms and businesses to generate their own energy, concludes a new report released today.
Putting more wind power on the grid
Wind turbines tend to be overshadowed by solar power projects, which get most of the attention from the public and policymakers. That's the case again in a new government plan for renewable energy projects in the California ...
Americans continue to use more renewable energy sources
Americans used more natural gas, solar panels and wind turbines and less coal to generate electricity in 2012, according to the most recent U.S. energy charts released by Lawrence Livermore National Laboratory.
