When people think or energy sources, they mostly think of coal, natural gas and oil, these fuels have been the source of energy for a number of years. One problem however is that they are limited in supply and availability.
Estimates have shown that the currently available sources will only meet our current energy demands for about 50 to 70 years or so. In order to find alternative sources of energy the world has decided to pursue renewable energy sources. However even renewable energy sources have their advantages and disadvantages too.
The available renewable energy sources that we have include solar, hydro, wind, geothermal, ocean and biomass. The most common of these advantages is that they are clean energy sources and do not pollute the air. They also do not contribute to …

Using Solar energy you can create electricity to power RVs, residential homes and commercial properties. There are a variety of solar power systems available. Quite often the choice of which to go for is obvious but in other situations you may have to weigh up the pros and cons. This article will detail some of the options and explain the considerations.
If we consider an RV, for example, the ideal solar power system would be a portable system. These systems are economical, as they have a smaller number of solar panels and batteries than a larger stand-alone system. They may be moved around so that they can make the most of the sunny conditions depending on your location.
The basic set up of a stand alone system for generating electricity is one …

As the myth around global warming begins to unravel and Operation Desperation sets in, it’s important for the public to know why biofuels aren’t the answer to solving global warming. For those that don’t know, biofuels are alternative energy sources derived from living matter, as opposed to fossil fuels, such as oil, which are derived from nonliving matter. The most common biofuel is a blend of gasoline called E85, which means it’s 15% gasoline and 85% ethanol. However, the gasoline and ethanol content changes depending on the season. During cold weather, more gasoline needs to be added to the mixture to ensure the fuel works properly, so E85 is at least 70% ethanol.
If biofuels are going to reduce our dependency on foreign oil, what’s the big deal? Ethanol, without consideration …

As fossil fuel based energy prices reach record-highs and the sever environmental effects of processing that fuel are becoming increasingly dangerous, alternative energy resources must be harnessed to continue supplying the huge demand for energy in an environmentally friendly and economic way.
There are several alternative energy sources which are already used to supply energy to millions of people. These energy sources include wind, Geo-thermal sources and solar, amongst others.
Solar Energy Characteristics:
Energy derived from the sun has several significant characteristics which makes it the most promising energy source of the future. These characteristics include:
 
Clean energy -converting this type of energy to electricity does not emit any greenhouse gases and does not produce any waste. Renewable – sun-derived energy supply is endless. Free – it is available for free. Anyone can install …

Losing Continents
Climate change scientists tell us what we may lose in the future. Already they reckon the ozone hole is as large as Antarctica.
I learned from my gardening teacher, Klaus Lautenberger, that we have lost soil the size of North America. We lose it through wind and rain. Remember the Grapes of Wrath? John Steinbeck’s classic told the economic and personal dislocation experienced by the climate catastrophe experienced in the American Midwest during the Great Depression of the early 1930s.
One of my fellow students exclaimed, “But then soil is more costly then oil!”
Yes, soil is precious. In Ireland we have lost a huge amount through lashing rain and bellowing wind. We use wind turbines to create renewable energy quite efficiently here in the Northwest. After a heavy rain the streams …
