Delaware May Become Home To The Largest Wind Park In The U.S.

Delaware may become home to the largest wind power plant in the United States. A wind energy developer, Bluewater Wind, hopes to build a 600-megawatt wind park in the waters just off Delaware’s coast. The wind park would power 130,000 homes for over 20 years, at price cheaper than coal or gas, according to Bluewater Wind’s founder Peter Mandelstam. His …

IKEA To Start Charging For Plastic Bags

IKEA will begin charging customer five cents for disposable plastic bags. IKEA hopes that this move will be the first step in ending their use altogether. The company said the decision was aimed at reducing the amount of plastic bags that are thrown away. IKEA is believed to be the first major retailer in the U.S. to undertake such a …

New Biofuel Cells: Electricity From Hydrogen and Thin Air

Science Daily reports that British scientists have developed a “biofuel cell” that generates electricity from air spike with small amounts of hydrogen. These cells are an inexpensive, renewable alternative to “fuel cells” that have been closely associated with the “hydrogen economy”. At a recent meeting of the American Chemical Society, Fraser Armstrong, described how his research group at Oxford University …

Danish Island Is Energy Self-Sufficient

The goal of the Danish island of Samso, home to about 4000 people, is to power their island with completely green power. They heat their homes with grass burned in a central heating system. Their electric come from the wind, and they power their vehicles on biofuel which they also grow. Since 1998, Samso began converting its energy into renewable …

Model Fuel-Cell Car Uses Solar Power

Here is a model race car that runs on hydrogen produced by a small solar cell. The car uses a real fuel cell and its own on-board hydrogen storage system. To create free hydrogen fuel, you just add water to the stations tank. Fueling is animated by a special blue light display. The car will operate for about 4 minutes …

“Electranet” Could See Light Of Day

With his new-found movie star clout, former Vice President Al Gore has begun an aggressive environmental crusade for ground-breaking technology and policy changes to the nation’s electricity grid. Using the momentum of his Oscar-winning documentary on global warming, Gore is advocating a decentralized “smart grid” that would allow anyone to set up their own generator and buy or sell surplus …

Major Solar Power Plants Opens In Portugal

One of the world’s largest solar energy plants, covering the hills of a valley dotted with olive groves in southern Portugal, started delivering electricity to about 8,000 homes on Wednesday. The solar panels, which are raised around 2 meters off the ground, cover an area of 60 hectares (150 acres) and produce 11 megawatts of electricity in one of Europe’s …

Solar Powered 12 Volt Battery Charger

Solar powered 12 volt battery chargers are small solar panels that trickle charge your car’s battery while the sun is shining. Basically, the solar charger provides a small amount of power to the battery, so that if you leave your car’s door open you won’t be left with a dead battery. This reminds me: I’ve always wondered why cars don’t …

Zero-Energy House: It Uses Solar Power and Hydrogen

The New York Times just published a report on home that uses a unique system to generate hydrogen using solar power. The system was built by Mike Strizki, the 50-year-old director of Advanced Solar Products, a solar installation company, designed a backyard power plant that provides all the house’s energy, using a combination of solar panels and solar-generated hydrogen. Here’s …

Cube Gadget For Fridges Could Slash Electrical Use

The e-cube, invented by British engineers, significantly reduces the energy used by fridges and freezers, which are estimated to consume about a fifth of all domestic electricity in the UK. The one-size-fits-all, retrofit, wax device, barely three inches wide, fits around the temperature sensor, to more accurately reflect the temperature of the contents. It said to cut power usage by …
