Wind, Solar...Coconuts: Small Island Developing States Commit to Renewable, Sustainable Energy for All
May 15, 2012 03:20 PM - Andrew Burger, Global Warming is Real

Typically heavily reliant on the cost of high and volatile diesel and fossil fuel imports, small island developing states are also on the front line when it comes to having to cope with climate change. Now they're realizing there's a lot in the way of cleaner, more efficient and less costly power and fuel resources right at home. They're increasingly, if belatedly, establishing ambitious renewable energy programs and setting aggressive targets to employ local renewable energy resources to reduce CO2 and greenhouse gas (GHG) emissions, working with a range of international development agencies, public and private sector partners domestic and foreign, in doing so.

Alternative Fuels — Cars That Run on Natural Gas

Dale Cooper
Find out how an alternative fuel used all over the world may find its way into American vehicles. Natural gas is abundant, clean and already a part of our everyday lives—and it may be the next big alternative fuel. In the world of alternative fuels, electric, hydrogen and even hybrid vehicles get most of the attention. Not many people are aware of another alternative automotive fuel that burns cleaner than gasoline, is found abundantly in the United States and is already in heavy use around the world: natural gas. Natural gas is by no means a new fuel; it’s been used to heat homes and cook food in gas stoves for more than a century. But only recently have automotive technicians begun exploring the possibility of using natural gas as an alternative to gasoline in automobiles here in the United States. How it Works When used in automobiles, natural gas comes in two forms: ”˘ Compressed natural gas (CNG) ”˘ Liquefied natural gas (LNG) Both forms require storage in cylinders that are often located in the trunk of the vehicle. When being burned by an engine, natural gas works very similarly to gasoline; vehicles that run on natural gas will have spark plug timing and compression optimized for that type of fuel.

Cinnamon Is Good For You in More Than One Way

April 24th, 2012
Now, I may love cinnamon more than the next guy. I put it in my oatmeal, I put it in my applesauce, and I sometimes even put it in my chicken parmigiana (it adds a really sweet contrast to it). But who knew that it could make you live a healthier life. A very common [...]
