The global financial crisis dominated the news media in the second half of 2008. The crisis is certainly negatively affecting the sustainable energy market in the short term. On the other hand, the crisis has generated broad public demand for government investments that create employment and stimulate the economy.
In 2007, and during the first half of 2008, all the signs for PV were positive. There was a very attractive feed-in tariff in Spain, credit lines were easy to get, oil prices were rising and economies growing rapidly. Now, the industry faces a strong head wind with oil prices very low, economies in recession, finance hard to obtain and the world's largest market regulated by a cap with a 30% lower feed-in tariff.
India, the world's second-most populous country, is facing a looming energy crisis. Soaring oil prices, and continued dependence on a few countries for oil, has led to the use of renewable energy sources to secure energy.
Does Jatropha risk a backlash from public opinion? Jatropha proponents have justifiably been promoting its benefits as a sustainable source of oil crops for years, but from the agro-business side it seems to be evolving in the opposite way: monoculture, hurting biodiversity, causing deforestation and competing for land with food crops.
Federal and state rebates can save you as much as 50% on your total cost, so it is important the company is taking every advantage of available rebates.
This article presents the novel combination of a Pneumatic Power Tower and Solar Power Tower in an Open Pit Mine: called a "Pit Power Tower" (PPT).
The new generation of clear solar control window films offer different choices, featuring the ability to block solar heat without blocking the sun's natural daylight. The best among them are those offering true Infrared Reflectance, using Southwall Technology's "heat-mirror" technology to ensure that solar heat is reflected away from the window and not absorbed into the building or the window glass.
The media, policymakers and even those in the industry have let evacuated tubes languish as a mere cousin to solar electric.
There has been a lot of progress made recently in improving energy efficiency, but it's important to look at the process and your house as a whole - an improvement in just one area of your home will not necessarily work.
How many of us defrost frozen meat with running water instead of letting it thaw in the fridge? How many times do you use the hose to sweep off the driveway when a broom can be just as effective?
After several weeks of economic doom and gloom in the news we walked into a room full of squeeky new booths full of optimistic and excited people showing and talking about a new world where responsible companies lead the way to a renewable energy future. How refreshing is that!
The single solar panel provides dc power to assist the fan that moves air across the outdoor coil, a key part of any home comfort system. The fan has an ac motor for normal operation and a special dc motor that assists whenever sufficient sunlight is available.
The aviation industry produces only about one-ninth as much carbon dioxide as motor vehicles do. However, environmentalists are vocal about emissions from aviation, because they tend to go into the upper atmosphere, where some scientists say the impact is greater.
There is a rule in communications: If you don't manage your message, someone else will. Each day people throughout your organization have conversations with a variety of people outside the organization.
Data loggers can provide valuable information for nearly every aspect and scale of green design. For example, a facilities manager can monitor temperature in a fifteen-story office building over the summer to check whether the fans in the building's cooling tower need adjustment.
