Spanish Solar Company SOLARIG Building 8 PV Parks in Italy

Posted: 31 Oct 2009 09:15 AM PDT


SOLARIG, a company based in Spain that incorporated about four years ago, just began construction of eight photovoltaic parks in Italy this month. The parks will provide 8 MW of energy in total. Over the next few months, it plans to construct photovoltaic projects producing 30 MW throughout different regions of Italy.

But this is just the beginning. SOLARIG has a more global vision.

Developing Residential Solar Installation Monitor

Posted: 31 Oct 2009 04:14 AM PDT

rooftop solar

A partnership between two companies will develop a home energy monitoring device for residential solar power installations.

Two startups – Tendril Networks, known for its home energy monitoring technology and Fat Spaniel technologies, a solar panel monitoring company – make up the partnership. The purpose of the partnership is to develop a monitoring device for homes that can gauge the sun’s intensity for any particular time and automatically adjust, or even shut down, home appliances as needed.

Nanomaterial Being Produced By the Ton

Posted: 30 Oct 2009 10:27 PM PDT


Nano carbon Graphene is already being produced in decidedly non-nano quantities by Ohio-based Angstron. Yet the atom-thick nano-material was discovered so recently that researchers are still in the process of discovering what to use it for.

Graphene is an extremely low density material, almost an atomic-scale chicken wire made of carbon atoms and their bonds. It has been the focus of much research because of its exceptional electrical, mechanical and optical properties. It holds great promise in renewable energies.

Among the so far underutilized advantages Graphene offers are that it is fifty times stronger than steel, and it has five times the conductivity of copper, with only one quarter of the density.

Northeast Adds 17 Gigawatts of Renewable Power to Meet RPS

Posted: 30 Oct 2009 08:26 PM PDT


Renewable energy comprised more than half the energy added this year to the Northeast grid, comprising part of Canada and 6 US states. 17 GW of renewable energy projects in the region will be completed in the next five years.

It is no coincidence that each of these states has a state renewable portfolio standard which requires utilities to add an increasing percent of renewable power to the grid each year. New York’s RPS requires 24% by 2013, Maine:40% by 2017(met), Vermont:20% by 2017, New Hampshire:16% by 2025, Rhode Island:16% by 2019, and Connecticut:27% by 2020 )

The Renewable Portfolio Standard is a sure way to get more homegrown climate-friendly renewable power on the grid and is up for votes yet again this year (in the American Clean Jobs & American Power Act) after multiple previous attempts to pass it.

Chinese Manufacturer First to Export Wind to U.S.

Posted: 30 Oct 2009 05:33 PM PDT

A-Power Energy Generation Systems won one aspect of the clean energy race and made history, as it will become the first Chinese manufacturer to export wind turbines to the United States. A-Power Energy Generation Systems and a consortium of Chinese and American companies — U.S. Renewable Energy Group, Cielo Wind Power, and the Shenyang Power Group — are planning to build a 600-megawatt wind farm in West Texas.

The project, which could power as many as 180,000 homes, will require 240 2.5-megawatt turbines and the farm will occupy 36,000 acres of land in West Texas. Nearly shovel ready, the construction effort is projected to create about 30 permanent jobs and 300 temporary ones. Ground-breaking on the wind farm is slated for March of 2010.

Using Waste Heat Energy for Industrial-Scale Air Conditioning

Posted: 30 Oct 2009 04:51 PM PDT

Here’s a low carbon cooling technology that uses hot water from waste to make A/C without fossil fuels, saving 80% over fossil-fueled chillers.

This industrial scale chiller from the Chinese company Broad Central Air can convert many different kinds of waste heat into air conditioning. The waste heat can come from many industrial sources, including what the Chinese site calls “town gas”  - methane from town landfill, collected and burned to generate heat.

Hawaii Follows California with a Renewable Energy Feed-in Tariff

Posted: 30 Oct 2009 03:43 PM PDT


Earlier this month, Governor Schwarzenegger signed legislation to buy solar power from relatively small private generators for rates above market value. Hawaii is next in line with this European-style tariff — the Hawaii Public Utilities Commission and Governor Lingle just recently set a similar initiative for Hawaii.

Hawaii’s initiative will make it possible for homeowners and businesses to sell power they generate from small to medium-scale renewable energy projects (i.e. solar panels) to Hawaii’s main power producers at higher than market-value rates.
