Solar Radiation and its Use in Solar Hot Water Applications

When choosing a solar hot water system, it is important to understand the difference between direct beam radiation and global radiation. This is important because solar concentrators, like the SolarBeam Concentrator rely on direct beam radiation to create solar hot water, whereas flat panels rely on global radiation, which is more diffused energy.

Solar Heating Costs Drop From 15 year Payback to 6 Years with SolarBeam from SolarTron Energy System

The SolarBeam Concentrator can provide up to 13kW of heat per hour (44,300 BTU's). SolarBeam is 262%more efficient than flat panels. The payback period is only six years, compared with 20+ years for flat panel or 15 years for evacuated tube when used in process heat applications (above 140 F)

Ottawa Takes Part in Ontario's Green Energy Act Incentives

City council in Canada's capital region may soon approve a deal to partner with Hydro Ottawa to build solar energy installations on twenty municipal buildings. Councillor Maria McRae, Chairwoman of Ottawa City Council's Environment Committee, made the announcement January 11 at a City Hall press conference. If approved, the $220,000 plan will create green energy and clean air for the city and countless jobs for the province's solar installers.

Investors Loved Wind, Solar, Efficiency in 2010

Investors loved the opportunities of the wind and solar sectors and the quick returns of energy-efficiency firms in 2010, according to a U.S. market report (PDF) by Peachtree Capital Advisors. The wind industry had close to $4.8 billion in transaction value in 2010, which included private fund-raising deals, initial public offerings, and mergers and acquisitions. Solar generated a transaction value of $3.2 billion, and energy efficiency, which includes smart grid and LED lighting companies, followed with $2.5 billion. The transaction values run parallel to the cleantech investing numbers for 2010, which found that solar startups continued to draw the most money in venture capital investment last year, while energy-efficiency startups garnered the largest number of deals, according to the Cleantech Group. However, given utility-scale wind is a more matured market, there are fewer investments in next wind technology startups.

Los Angeles gets country's first fully alt-fuel transit fleet

Metro is now the only major transit agency in the U.S. with a fleet run entirely on alternative fuels. Officials say the shift has sharply cut emissions of cancer-causing pollution. After almost two decades of effort to reduce vehicle emissions, the Los Angeles County Metropolitan Transportation Authority retired its last diesel bus Wednesday and became the only major transit agency in the nation with a fleet that is totally equipped with alternative-fuel technologies. In an urban area where diesel buses began operating in 1940, the MTA now has 2,221 buses powered by compressed natural gas, as well as one electric bus and six gasoline-electric hybrids. Transit officials estimate that the elimination of diesel engines has reduced the release of cancer-causing particulates from the bus fleet by 80% and greenhouse gases by about 300,000 pounds a day in one of the smoggiest areas of the country. MTA officials say that compressed natural gas buses cost more to buy and maintain than those powered by diesel but that the increased expenses are offset somewhat over the long run by lower fuel costs.
