The incandescent lightbulb that wastes 90% of the electricity as heat is dying, we all know that. But a new breakthrough in solid state lighting might also kill compact fluorescent lightbulbs (CFLs) faster than some expected. Scientists at Purdue University have figured out how to manufacture LED solid-state lights on regular metal-coated silicon wafers (more details below). What this means is: much lower costs.

Scientists from the Universidad Carlos III of Madrid (UC3M) and the Consejo Superior de Investigaciones Científicas (CSIC) have developed an environmentally friendly cooling technology that does not harm the ozone layer. This is achieved by using solar energy and therefore reducing the use of greenhouse gases.

China needs a lot of energy to power its economy and the country's reliance on coal has led to major problems with unsafe work conditions and pollution. By 2006, China's energy requirements had become the second highest in the world, doubling its needs from the past decade.

There have been major strides in producing everything from sandals to military hardware in more eco-friendly ways. Likewise, the reduction of waste has also been improved, through both new technology and behavioral changes. But perhaps the most intriguing sector of the "sustainability industry" is the one populated by companies and organizations capturing waste and converting it into useful, carbon-neutral resources.

If giant solar thermal power plants spread across the desert are like a mainframe, Sopogy is making the equivalent of a personal computer. The Hawaii-based company on Tuesday at the Intersolar 2008 conference will show off the latest version of its MicroCSP--essentially a shrunk-down version of concentrating solar power (CSP) equipment used in power plants.

Last week, the Japanese newspaper Nikkei caused a buzz by reporting that a redesigned Toyota Prius, to be released next year, will come equipped with solar panels. Toyota spokespeople will neither confirm nor deny the report, but several companies already offer solar roof kits for the Prius, and researchers at the U.S. Department of Energy's National Renewable Energy Laboratory (NREL), in Golden, CO, have been testing one on a Prius modified to plug into the electrical grid.

The ocean's waves have enough energy to provide two trillion watts of electricity, according to the Department of Energy's office of Energy Efficiency and Renewable Energy. Extracting that enormous resource of power, however, has proved to be a herculean challenge.

University Park, Pa. -- A greener, less expensive method to produce hydrogen for fuel may eventually be possible with the help of water, solar energy and nanotube diodes that use the entire spectrum of the sun's energy, according to Penn State researchers. "Other researchers have developed ways to produce hydrogen with mind-boggling efficiency, but their approaches are very high cost," says Craig A. Grimes, professor of electrical engineering. "We are working toward something that is cost effective."

Dubbed the "missing greenhouse gas," nitrogen trifluoride (NF3) was found by a recent study to have a global climate impact 17,000 times greater than carbon dioxide. The chemical is found in the LCD panels of cell phones, televisions, and computer monitors, as well as in semiconductors and synthetic diamonds. The chemical is not one of the greenhouse gases monitored by the Kyoto Protocol, due to the fact that LCDs were not produced in significant quantities when it was drafted.

A new way of capturing the energy from the Sun could increase the power generated by solar panels tenfold, a team of American scientists has shown. The new technique involves coating glass with a specific mixture of transparent dyes which redirect light to photovoltaic cells in the frame.

At present, China produces just over 6 gigawatts (GW) of wind energy, making it 5th in the world for total wind energy. (Germany leads with 22.2 GW.) However, with China’s massive push for 21st Century renewable technologies, we shouldn’t be surprised if China achieves 100 GW by 2020 say energy experts.

In this week's New Yorker, Elizabeth Kolbert wrote about the Danish isle of Samsø, which over the past 10 years, has gone from exclusively using fossil fuel energy sources, to living exclusively off renewable energy. Using a combination of onshore and offshore turbines, private mini-turbines, solar panels, straw-burning furnaces and biofuels, the 4,300-resident island has become a sort of a sandbox for green experimentation.
