While Europe invests in wind energy, Norwegian hydropower offers the key to stable electricity supplies. The key driver of the development of a northern European offshore power grid is the massive investment being made in wind power in the Baltic and in and around the North Sea. The aim here is to reduce CO2 emissions by as much as between 80 and 95 per cent by 2050.
Renewable energy sources such as wind-powered generators can be more reliable and efficient by better controlling the process of getting electricity onto the power grid, according to new research.
Many owl species have developed specialized plumage to effectively eliminate the aerodynamic noise from their wings -- allowing them to hunt and capture their prey in silence. A research group is working to solve the mystery of exactly how owls achieve this acoustic stealth -- work that may one day help bring “silent owl technology” to the design of aircraft, wind turbines, and submarines.
A new estimate of bat deaths caused by wind turbines concludes that more than 600,000 of the mammals likely died this way in 2012 in the contiguous United States. The estimate used sophisticated statistical techniques to infer the probable number of bat deaths at wind energy facilities from the number of dead bats found at 21 locations, correcting for the installed power capacity of the facilities. The high mortality is worrisome because bat populations grow only very slowly.
Think about a time you've been a passenger in a car and stuck your hand out the window. As your speed increases, so do the vibrations in your hand. Trying to keep those fingers steady as the wind whips around them at 75 mph gets pretty tricky, right?
Growth in offshore wind generation is expected to play a major role in meeting carbon reduction targets around the world, but the impact of construction noise on marine species is yet unknown. A group of scientists have developed a method to assess the potential impacts of offshore wind farm construction on marine mammals, particularly the noise made while driving piles into the seabed for wind turbine foundations.
Researchers have found staggering and spacing out turbines in an offshore wind farm can improve performance by as much as 33 percent.
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.
Researchers have found that real contribution to emissions targets is positive even in energy markets with high penetration of wind energy.
A new field strength measuring system is to predict possible interferences in the coexistence of wind farms and radar facilities.
New research quantifies the potential impacts of increasing wind and solar power generation on the operators of fossil-fueled power plants in the West. To accommodate higher amounts of wind and solar power on the electric grid, utilities must ramp down and ramp up or stop and start conventional generators more frequently to provide reliable power for their customers -- a practice called cycling.
Findings show carbon pollution from power plants can be cut cost-effectively by using wind, solar and natural gas. It’s less costly to get electricity from wind turbines and solar panels than coal-fired power plants when climate change costs and other health impacts are factored in, according to a new study.
In the long sprint to find new sources of clean, low-cost power, slow and steady might win the race -- the slow-moving water of currents and tides, that is. Just as wind turbines tap into the energy of flowing air to generate electricity, hydrokinetic devices produce power from moving masses of water.
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 batteries for later use seems like an obvious solution. But a new study finds that when you factor in the energetic costs, grid-scale batteries make sense for storing surplus solar energy, but not for wind.
A new study indicates that by 2025 wind and solar power electricity generation could become cost-competitive without federal subsidies, if new renewable energy development occurs in the most productive locations.
After analyzing more than 50,000 home sales near 63 wind facilities in 27 counties across nine US states, researchers were unable to uncover any impacts to nearby home property values.
