The sun produces immense amounts of energy which are transmitted right down to the earth’s surface. As soon as the sun’s light reach the earth’s surface the concentration of the heat directly coming from the sunlight is not as hot due to some of the heat energy is actually rerouted before it actually gets to the earth’s atmosphere. When the …

The sun creates immense amounts of energy which are transmitted down to the earth’s surface. As soon as the sun’s light reach the earth’s surface the intensity of the heat directly from the sun’s rays is not as hot basically because some of the heating happens to be rerouted before it reaches the earth’s atmosphere. When the sun is hot …

The sun’s light generates immense amounts of heat that are transmitted right down to the earth’s surface. When the sun’s rays reach the earth’s surface the power of the heat directly coming from the sun’s rays is not as hot due to some of the heat is actually rerouted right before it actually reaches the earth’s atmosphere.

Today’s guest post: The global warming or climate change enthusiasts have created a huge focus on saving the planet by promoting environmentally friendly products. Savvy consumers should be careful not to fall for this marketing gimmick called greenwashing. Many of the products we already use are friendlier to the environment than their so-called green counterparts. Pay close attention to the …

With a series of intensive solar projects under way, as much as 7.5GW in PV capacity could be added to the local power grid by 2015, more than half the state’s announced goal of achieving 12GW from all renewable sources—and with five more years to spare before the targeted 2020 deadline. What this shows is the likelihood of PV accounting in the future for a great portion of clean energy in California, Sheppard noted.

By Daryl J. Ehrmantraut Our future energy requirements depend on reaching the ‘holy grail’ of electricity generation – Finding a cheaper alternative to coal and other fossil fuels. The availability of an alternative energy source would also contribute significantly to energy self-sufficiency in North America. Every hour more energy from the sun hits the earth than the world’s entire population …

Photograph by Tim Wimborne, Reuters This story is part of a special series that explores energy issues. For more, visit The Great Energy Challenge. For years, the energy world has puzzled over how to harness the sun to make rooms cool. That may sound counterintuitive to those who think primarily of the uncomfortable heat beating down on roofs and windows …

the report shows that in 2010, renewable energy supplied an estimated 16% of global final energy consumption and delivered close to 20% of global electricity production. Renewable capacity now comprises about a quarter of total global power-generating capacity. Including large and small hydropower (an estimated 30 GW added in 2010), renewable energy accounted for approximately 50% of total added power-generating capacity in 2010. In 2010, existing solar water and space heating capacity increased by an estimated 25 gigawatts-thermal (GWth), or about 16%.

According to the latest survey conducted by EnergyTrend, manufacturers indicated that they are conservative about September orders and the PV market of 3Q11. On the other hand, the spot price of polysilicon remained at a high level. The Chinese market demand still stayed high while other markets showed signs of slowing. According to EnergyTrend, downstream manufacturers are conservative about spot price trend of polysilicon, primarily because most orders from large manufacturers are signed on contractual terms, and few make purchase on the spot market.

How are you with your knowledge of solar energy and solar energy related issues. Well the good folks over at National Geographic have put up a very cool quiz that tests your knowledge. I took it. Why don’t you? Solar Energy Quiz Here

We no longer need to burn fossil fuels to produce usable energy. Today there are many alternative forms of usable energy available to us. Choosing to utilize other forms of renewable energy such as solar panels not only reduces our carbon footprint and the impact that we have on the world, but also provides us with a sustainable energy source …

LEED-certification is often the first guideline that comes to mind when considering green building best practices. While LEED-certified modular buildings can and have been constructed, just like traditional construction, it only comes at great expense. There are many simple, cost-effective alternatives that modular builders use every day to reduce construction waste and make their buildings more energy efficient.

In their new book, CLEAN ENERGY NATION Congressman Jerry McNerney, a renewable energy expert, and technology writer Martin Cheek assess the positive and negative aspects of various alternatives.

“American Vision Solar is dedicated to enhancing home energy efficiency, and we’re thrilled to be able to offer our customers such a unique PPA,” said Bill Herren, President and CEO for American Vision Solar. “We pride ourselves on providing impressive customer service, which is why it was our priority to create an agreement that would truly benefit the homeowner.”

In the midst of the worst economic downturn since the Great Depression, the clean economy expanded by 8.3 percent, says the report. Efficiency, renewable energy, biofuels and other clean industries accounted for 2.7 million US jobs in 2010. To put that number in perspective, that’s more jobs than you’ll find in fossil fuels or biosciences, but still less than information technology

Five major Great Lakes national parks are already feeling the impact of climate change in the forms of rising temperatures, decreased winter ice, eroding shorelines, spreading disease, and a crowding out of key wildlife and plant life, according to a major new report issued today by the Rocky Mountain Climate Organization (RMCO) and Natural Resources Defense Council (NRDC).

In addition to presenting its extended warranty, Silicon Energy recently has been able to reduce its pricing as a result of manufacturing improvements and strengthened vendor relationships.

It is more difficult to give an unqualified answer to the second question. Even a traditional school cannot guarantee the student a job after graduation. But online degrees are as well respected as any from a traditional school.

Solar panels for homes which convert the sun’s rays to generate electricity have many great benefits to homeowners and our planet altogether. Nowadays, with so many homeowners switching to solar energy to power their electricity needs, solar energy has grown in demand. Its efficiency, durability and environment friendliness have contributed in its popularity. 1. Economical Electricity rates have been sharply …
