Renewable Energy Cost Analysis for the US

The high cost of fossil fuels coupled with CO2 emissions threatening climate change has led to an influx of proposals for renewable energy projects. However, the choice as always will come down to costs and which renewable energy type has the best short-term and long-term economic potential.

Guide to Harnessing the Wind for Energy

Wind offers an endless supply of energy, but the big question is how can we take advantage of this in the most efficient way? In this guide to harnessing wind power for energy we’ll look at the current technology and the future potential.

Ionizing Air and Ozone

The ozone layer located high in the stratosphere protects us from the sun’s harmful high frequency UV rays. This layer is getting thinner due mostly to anthropogenic activities along with the production of ionized air, prompting an examination into the relationship between ionized air and ozone.

Making Fossil Fuels Less Hazardous for Our Environment

Coal-fired power generating facilities spew vast quantities of the greenhouse gas CO2 into our atmosphere. However, there is a technology that could allow these facilities to keep operating, but it could also possibly have as much of an impact on greenhouse gas emissions as renewable technologies.

Straw Bales as Fuel to run Barley Dryer

Farmers who grow barley and other cereal crops have had difficulty reaping their harvest due to wet weather prevalent in many parts of the world. This has caused them to reap wet barley resorting to the use of expensive grain dryers to reduce the humidity content before it is acceptable for malting.
