Vestas' investment in Brighton will total about US $300 million, and will secure an annual production capacity of 2,000 blades and 1,400 nacelles.

The Solar Energy Industries Association (SEIA) has released its 2008 U.S. Solar Industry Year in Review, highlighting a third year of record growth for the solar industry. According to the report 1,265 megawatts (MW) of all varieties of solar power were installed in 2008, bringing total U.S. solar power capacity up 17 percent to 8,775 MW. California was the leader among state grid-tied PV installations with 178.6 MW, New Jersey followed with 22.5 MW installed, Colorado was next at 21.6 MW, Nevada installed 13.9 MW and Hawaii with 11.3 MW. The 2008 figure included 342 MW of solar photovoltaic (PV) installations, 139 MWTh (thermal equivalent) of solar water heating, 762 MWTh of pool heating and an estimated 21 MW of solar space heating and cooling.

Vice President Joe Biden and Energy Secretary Steven Chu today announced plans to invest $3.2 billion in energy efficiency and conservation projects in U.S. cities, counties, states, territories, and Native American tribes. The Energy Efficiency and Conservation Block Grant program, funded by President Obama's American Recovery and Reinvestment Act, will provide formula grants for projects that reduce total energy use and fossil fuel emissions, and improve energy efficiency nationwide. "These investments will save taxpayer dollars and create jobs in communities around the country," said Vice President Biden. "Local leaders will have the flexibility in how they put these resources to work - but we will hold them accountable for making the investments quickly and wisely to spur the local economy and cut energy use."

President Obama today announced over $467 million from the American Reinvestment and Recovery Act to expand and accelerate the development, deployment, and use of geothermal and solar energy throughout the United States. The funding announced today represents a substantial down payment that will help the solar and geothermal industries overcome technical barriers, demonstrate new technologies, and provide support for clean energy jobs for years to come. Today's announcement supports the Obama Administration's strategy to increase American economic competiveness, while supporting jobs and moving toward a clean energy economy. "We have a choice. We can remain the world's leading importer of oil, or we can become the world's leading exporter of clean energy," said President Obama. "We can hand over the jobs of the future to our competitors, or we can confront what they have already recognized as the great opportunity of our time: the nation that leads the world in creating new sources of clean energy will be the nation that leads the 21st century global economy. That's the nation I want America to be."

The whole thing is happening without flashy ad campaigns, so it's not surprising if you've never heard of municipal solar financing. But the financing program, also known as property tax financing, is a veritable underground solar revolution. It all started in Berkeley, CA with the Berkeley FIRST Program, which allows homeowners to pay for solar panels through property tax bills over a 20 year period. The bills carry a fixed interest rate and stay with the house, so there's no need to worry about paying for panels on a house you don't live in anymore. The Berkeley program was so popular that California passed the AB811 bill to let any interested city in the state launch a similar program.

Large-scale solar power is beginning to take on the job of meeting the demands made by California's air conditioners for electricity. Pacific Gas & Electric and Brightsource Energy today announced they have expanded a series of solar power contracts for a total of 1,310 megawatts of electricity - enough to power 530,000 California homes during peak hours with energy from the Sun. Completion of the first project will nearly double the amount of solar thermal electricity produced in the United States.

During a visit to Fort Wayne, Indiana, where he toured a manufacturer of geothermal heating pumps (GHPs), U.S. Energy Secretary Steven Chu today announced nearly $50 million from the American Reinvestment and Recovery Act to advance commercial deployment of the renewable heating and cooling systems, which use energy from below the Earth's surface to move heat either into or away from the home or building. The expanded manufacturing and installation of GHPs could aid in the creation of new jobs while reducing the use of fossil fuels. "The heat from the Earth represents a significant energy resource that can be tapped to reduce emissions contributing to climate change." said Secretary Chu. "Expanded use of GHPs in the United States will create new jobs for engineers, manufacturers and technicians while at the same broadening our nation's clean and renewable energy portfolio."

The U.S. Bureau of Labor Statistics states that there are 136,000 refuse and recyclable material collectors in the country.

In the United States, the laws require compulsory reporting and verification of the greenhouse gas emissions generated by industries covered in both the voluntary and the regulatory sectors.

In pursuit of Governor Deval Patrick's goal of 2,000 megawatts of wind power in Massachusetts by 2020, the Secretaries of the Executive Office of Transportation (EOT) and the Executive Office of Energy and Environmental Affairs (EEA) announced a project to install a utility-scale wind energy project on state land adjacent to the Massachusetts Turnpike's Blandford Rest Area. "This wind energy project is good for the environment and it will help create jobs within our clean energy economy." -- Massachusetts Governor Deval Patrick Following studies showing significant wind power potential, the Massachusetts Turnpike Authority (MTA) today issued a Request for Proposals (RFP) to install wind power at the 68-acre site in western Massachusetts.

I read U.S. opens way for wind power off coast and wondered "what's in it for me"? The federal government has cleared the way for developers to plant wind farms in offshore waters on the Outer Continental Shelf, a move that could have a significant impact for North Carolina. ... Eventually, the regulations could help shape energy production in North Carolina, where the Outer Banks jut sharply into the Atlantic. The area has some of the strongest and steadiest winds on the East Coast, according to a report from the U.S. Department of the Interior. ... In a scheme similar to some offshore oil and gas drilling leases, states would get about 27 percent of the revenue sent to the federal government from offshore wind and hydrokinetics leases.

olar domestic hot-water systems don't grab as many headlines, probably because they're not considered as high-tech as their solar PV cousins, where science is pushing the boundaries of sunlight-to-electricity conversion. I'm always surprised that residential solar thermal systems don't get much attention in the United States, particularly in the south where many homes have swimming pools (that need heating) and where the sun shines warm all year, making the payback dramatically better than PV. In Canada, where the conditions are less ideal, we seem for some strange reason to have a greater appreciation for rooftop solar thermal systems, and indeed, have many startups, such as EnerWorks, and academics spending considerable time improving on the technology.

In an ongoing effort to expand domestic renewable energy, U.S. Secretary of Energy Steven Chu today announced plans to provide $93 million from the American Recovery and Reinvestment Act to support further development of wind energy in the United States during a visit to the National Renewable Energy Laboratory today. Secretary Chu also announced more than $100 million in funding from the Recovery Act for NREL facility and infrastructure improvements. The funding will leverage the Department of Energy's national laboratories, universities, and the private sector to help improve reliability and overcome key technical challenges for the wind industry. These projects will create green jobs, promote economic recovery, and provide the investments needed to increase renewable energy generation. "Wind energy will be one of the most important contributors to meeting President Obama's target of generating 10 percent of our electricity from renewable sources by 2012," said Secretary Chu

New York City, United States [RenewableEnergyWorld.com] Close to US $155 billion was invested in 2008 in renewable energy companies and projects worldwide, not including large hydro. Of this $13.5 billion of new private investment went into companies developing and scaling-up new technologies alongside $117 billion of investment in renewable energy projects from geothermal and wind to solar and biofuels. The 2008 investment is more than a four-fold increase since 2004 according to Global Trends in Sustainable Energy Investment 2009, prepared for the UN Environment Programme's (UNEP) Sustainable Energy Finance Initiative by global information provider New Energy Finance. Of the $155 billion, $105 billion was spent directly developing 40 GW of power generating capacity from wind, solar, small-hydro, biomass and geothermal sources. A further $35 billion was spent on developing 25 GW of large hydropower, according to the report.

The article "Renewable energy potential" (Work&Money, Editor's Choice, June 7) provided interesting and useful information. Now it is time to begin to use more renewable energy in North Carolina. One of our electric utility companies should develop a pilot project in one of the high-wind areas off the North Carolina coast. This energy could be used to provide some power to Elizabeth City, Manteo or any other city located on the northern part of our coast. Our electric utility companies have many intelligent engineers who could use new technology to build wind turbines that can withstand strong storms. If other states in the Northeast can build wind farms off their coasts, then North Carolina can surely do the same.

A green parks designer makes sure that everything that is brought into or used in the park is as ecologically beneficial as possible to the natural state of the park. The green park designer may take into account certain challenges that are inherent and unique in every park system.

Smart grid technology is a long time away from being a nationwide, or even state wide reality. There are many stumbling blocks keeping many utility companies or cities from joining into the venture.

If a battery is used for many days, sulphite crystals form on the battery plates and it disrupts the flow of electricity. It may also happen when the battery is in a discharged or abused state.
