Solar power for less than $2 a day

Imagine a solar panel as affordable as a fancy new bicycle. A panel designed so simply that you can install one (or more) yourself, just outside your windows, in the course of an afternoon.

That’s the concept behind Oakland, Calif.-based Veranda Solar, a start-up founded last year by Capra J’neva and Emilie Fetscher, recent graduates of the product design program at Stanford University. J’neva and Fetscher dreamed up attractive, flower-shaped solar panels as part of their master’s project at the design school. “We created a starter solar system that expands as your budget does,” J’neva says.

Eco-Friendly Solar Power gains support

Measure B, known as the Green Jobs Initiative, would require the DWP to develop 400 megawatts of solar energy – enough to power 240,000 homes – over the next five years. It’s part of the city’s ambitious plan to develop 1,300 megawatts of renewable power by 2020.

Stimulus Bill and Solar Power- Let the Sun Shine: Stimulating Energy and Employment

* To maximize job creation, spending on renewable energy envisioned in the economic stimulus bill should be targeted at distributed generation projects, which use local labor for installation and increase the efficiency and reliability of power supply.

* Of the renewable energy sources, solar photovoltaic (PV) power is best suited to realize the potential of distributed and renewable energy generation. It matches peak energy demand most closely and offers the best opportunity to substitute expensive, centrally-generated electricity.

* Direct federal procurement and renewable energy loan guarantees, grants, and tax credits should favor smaller, distributed PV installations connected to the local distribution grid or generating electricity directly at the point of consumption.

* A significant share of the stimulus bill’s funding for modernizing the electricity grid should go to installing the electrical gear and smart power electronics and communication devices necessary for integration of distributed PV systems into the grid and better management of onsite generation, storage and use of energy.

Different Clean Air Technologies

Wind is a renewable energy source that emits no pollution. It is the fastest-growing “green” energy in the U.S. and provides light to the Statue of Liberty. Wind farms—clusters of huge windmills—produce electricity by using the motion of their blades to spin a shaft connected to a generator. Experts estimate that the electricity created in 2006 by America’s wind farms will displace some 15 million tons of carbon dioxide. Over five million acres of forest would be needed to absorb that much CO2. Some people oppose wind farms because they occupy large tracts of land and can sometimes harm birds, but most agree that their environmental costs are much lower than those of fossil fuels.

How Much of the World’s Energy Could Come from Solar and Wind Power

“The promotion of renewable energy involves political and economic instruments and business interests as well as research into sustainable energy technologies. Through this workshop we want to bring together key players in society to pave the way in a joint effort for more renewable energy. Not just in Denmark and Europe, but globally. We want to help developing countries find new ways for sustainable development, “says Director Henrik Bindslev, Risø DTU.

Hometown History: Solar energy pioneer has city ties

He developed a method of using flat-plate collectors that heated hundreds of gallons of water, and then kept the water warm at night by storing it in an insulated basin. Willsie then ran tubes into the heated water, and sent sulfur dioxide through the tubes, transforming it into a high-pressure vapor, which operated the engine. Essentially, Willsie became the first to harness solar energy for use when the sun wasn’t out.

Group says solar energy’s future bright in Texas

“Our economy is struggling and the unstable energy prices are only making things worse,” Seeley said. “But Texas has the technological prowess and vast resources of renewable energy from the sun, wind and crops that can revitalize our economy, power the nation, create thousands of high-paying manufacturing jobs, and renew Texas’ role as the energy capital of the world.”

Cheap High-Efficiency Solar Cells on the Horizon

“We hope that solar cells will one day be as thin as paper and be attached to the surface of your choice,” said co-author Hsiang-Yu Chen, a UCLA graduate student in engineering. “We’ll also be able to create different colors to match different applications.”

UCLA researchers create polymer solar cells with higher efficiency levels

“Previously, the synthesizing process for the polymer was very complicated. We’ve been able to simplify the process and make it much easier to mass produce,” said Jianhui Hou, UCLA postdoctoral researcher and co-author of the study. “Though this is a milestone achievement, we will continue to work on improving the materials. Ideally we’d like to push the performance of the solar cell to higher than 10 percent efficiency. We know the potential is there.”
