Heavy Coal User to build Solar Power Plants

NRG Energy, one of the United States' most coal-dependent utilities, on Monday signed a deal with California startup eSolar to develop solar power plants. The agreement calls for NRG to invest $10 million in Pasadena-based eSolar for the right to use the startup's technology to develop and operate three solar power projects in California and the Southwest that would generate 500 megawatts of greenhouse gas-free electricity. NRG ranks as one of the nation's dirtiest utilities, spewing 70 million tons of carbon dioxide annually from its coal-fired power plants. eSolar will use fields of mirrors to heat water to create steam that drives electricity-generating turbines.

GreenFasten™ solar panel roof mount hardware, watertight, USA made

The GreenFasten™ - GF1 system utilizes the patented watertight technology EcoFasten Solar® is known for. The flashing is fit with our EPDM rubber bushing and when used with a compatible EcoFasten Solar compression bracket (milled with countersink), a watertight seal is created, which protects the integrity of the roof. Requiring just a single fastener (lag bolt or self-drilling), GreenFasten provides the fastest install in the industry and will not void roofing manufacturer's warranties. Backed by IAPMO certification, GreenFasten delivers a mounting solution for all new or existing (retrofit) composition shingle roofs, and is the most cost-effective solution available. Like all of the solar roof mount solutions in our line of products, GreenFasten is made in the USA using recycled materials.
