Barriers remain

Article Abstract:

Research has shown that the supply of electric power should run to as much as 250,000 megawatts by the year 2010 to keep pace with demand. Renewable alternative energy sources could readily fill up this huge requirement if barriers disappear. With the existing abundance of oil and other fossil fuels, the world's governments are in no hurry to develop and exploit alternative sources. Short run expectations of profit have nudged out long term prospects of energy stability among businessmen. Furthermore, existing utilities display natural reluctance to new technologies because of cost considerations.

Tilting at windmills

Article Abstract:

Wind power has become a popular source of alternative energy in the US. It is considered the cleanest renewable power source and is relatively cheap considering that facilities are simple and capable of being mass produced. Wind equipment are expected to satisfy around 10% of the US energy requirements in the 1990s. Within the second decade of the next century, wind energy may account for about 25% of the country's energy demands. While the US had a headstart in the field, Europe has been able to catch up with Germany, the Netherlands and Denmark being the world's major markets for the industry.
