A common misconception is that solar technology was created in the 70’s. Yet, solar thermal systems have been in use for centuries. In fact, they date back to Roman times when hot water flowing beneath the floors heated not only baths, but also the living space. This simple concept is still being used today in radiant flooring. Solar thermal uses are expanding to areas such as heating and even cooling. However, the main use for solar thermal today is still in generating hot water for the home.
There is an ongoing debate over the impact of manufacturing biofuels. Skeptics argue that using crops for biofuels divert resources away from human consumption, therefore causing a choice in whether the crops are used for food or fuel. This reasoning connects biofuels to global hunger issues. This is based on the claims of some food industry groups that more than a quarter of corn crops are being diverted from food to ethanol production and yet the U.S. corn supply has outpaced demand since 1989. Most people with any amount of human compassion would easily say that food is definitely a higher priority than fuel. Before we oversimplify the situation, let us take a look at the factors.
According to a recently published bulletin from California’s Employment Development Department (EDD) photovoltaic (PV) solar installations are increasing around the country, with some areas like California experiencing dramatic increases. Some reasons for this relate to perpetually increasing energy costs, rebates, federal tax incentives and a gradual decrease in the pricing of solar modules to smaller dealers, installers and DIY customers. Bottom line is that the cost per watt is becoming more affordable.
Historically Hawaiian agriculture would have conjured up thoughts of sugar and coffee or pineapples and macadamia nuts. Times are changing. With a $2.4 million military grant, Hawaii is adding oilseed to its array of tropical crops. This switch to renewable energy will help to reduce the state’s $7 billion annual oil dependency as well as support the local economy. This two-year research project has already begun in Waialua, Oahu. In just 120 days, the island will become a contributor to biodiesel production.
It should be no surprise to hear that solar energy is growing at an amazing rate. In fact one would be hard pressed to avoid hearing something about renewable energy in the news. What is surprising is how well it is performing when compared to the U.S. GDP. A report published by Solar Energy Industries Association claims that "the U.S. solar market grew 67% in value in 2010” which is astonishing when compared to a GDP growth of only 2.8%.
Due to the continuing rise in electricity costs, energy reduction and consumption have become a top concern for homeowners today. In fact, a recent study conducted by the Solar Energy Industries Association (SEIA) showed that 49% of homeowners and businesses were considering installing solar panels now as a way of taking control of their energy costs. While most basic solar electric (PV) systems are good, homeowners and businesses can now consider more complete solar solutions. A new innovation in solar technology permits a solar system to generate not only electricity, but also heating, cooling and fresh air ventilation.
For years it’s been touted as common knowledge that energy efficiency and renewable energy raise the overall resale value of a home. Recently Lawrence Berkeley National Laboratory released a new study. This study reviewed resale value of homes with solar panels in California and found sufficient data to support the claims of increased resale value.
Fuel cells are touted by some as the energy source of the future. In fact, in 2003, the Hydrogen Fuel Initiative (HFI) program was implemented to foster the development of fuel cell technologies. Its goal is to produce practical and cost-effective fuel cell vehicles by 2020. The government has dedicated more than a billion dollars on fuel cell R & D. Now you may wonder why the government is spending so much on its development. Well, fuel cell technology is worth the investment.
With the popularity of renewable energy and going green, many companies these days are looking for ways to offset their carbon emissions. From this demand multiple voluntary producers of renewable energy have emerged to sell their carbon offsets in the unregulated renewable energy market. Thankfully, various independent organizations are here to help consumers know which green power products actually come from certified renewable energy sources.
The Environmental Protection Agency (EPA) has made it easy for organizations to purchase renewable energy by becoming an EPA Green Power Partner. This voluntary program offers a way to reduce environmental impacts of conventional electricity.
