Unprecedented contribution of wind power in U.S. Midwest

Unprecedented contribution of wind power in U.S. Midwest

Defying conventional wisdom about the limits of wind power, in 2012 both Iowa and South Dakota generated close to one quarter of their electricity from wind farms. Wind power accounted for at least 10 percent of electricity generation in seven other states. Across the United States, wind power continues to strengthen its case as a … learn more→

Solar energy incentives around the world

Solar energy incentives around the world

Sunlight is an unlimited source of non-polluting energy. Most power plants currently produce electricity with steam turbines. The heat to generate the steam is supplied by the combustion of fossil fuels such as oil, natural gas, or coal. Staggering volumes of carbon dioxide gas are produced through the combustion process. Carbon dioxide is a greenhouse … learn more→

Building the smart grid of the future: UCLA teams with Korea's energy research institute

Building the smart grid of the future: UCLA teams with Korea’s energy research institute

Imagine a home in which every appliance — computer, television, washing machine, refrigerator, air conditioner — can carry on a minute-by-minute “conversation” with the local power grid, allowing the devices to power down when the price of electricity is at a premium and to consume energy when it is cheapest. Such smart-grid technologies can lead … learn more→

Thoughts from a thorium ‘symposium’

Thoughts from a thorium ‘symposium’

You have probably heard at least a little about thorium. There are certainly advocates out there who strongly believe it could help solve the world’s energy problems. The idea is that thorium-based nuclear energy (it is nuclear) would have all the advantages of a uranium-based system – producing large-scale electricity with low emissions – without … learn more→

How it works: Water for electricity

How it works: Water for electricity

The United States uses many different technologies to produce electricity. It is important to understand the different impacts these technologies have on water resources. Water’s many roles in electricity Water is involved at many points in the process of producing electricity: Electricity Generation – More than 90 percent of U.S. power plants require cooling, a … learn more→

Hybrid power plants can help industry go green

Hybrid power plants can help industry go green

Hybrid cars, powered by a mixture of gas and electricity, have become a practical way to “go green” on the roads. Now researchers at Tel Aviv University are applying the term “hybrid” to power plants as well. Most power plants, explains Prof. Avi Kribus of TAU’s School of Mechanical Engineering and its innovative new Renewable … learn more→

A new approach to solar power

A new approach to solar power

Systems to harness the sun’s energy typically generate either electricity or heat in the form of steam or hot water. But a new analysis by researchers at MIT shows that there could be significant advantages to systems that produce both electricity and heat simultaneously. The new study incorporates thermoelectrics — devices that can produce an … learn more→

Hog waste producing electricity and carbon offsets

Hog waste producing electricity and carbon offsets

A pilot waste-to-energy system constructed by Duke University and Duke Energy this week garnered the endorsement of Google Inc., which invests in high-quality carbon offsets from across the nation to fulfill its own carbon neutrality goals. The system, on a hog finishing facility 25 miles west of Winston-Salem, converts hog waste into electricity and creates … learn more→
