Though mankind has harnessed the wind for centuries to produce energy, interest in this method of power generation has recently intensified as a result of both increases in conventional energy costs and the debate over the extent of humanity's responsibility for climate change.

Policy-makers and generating companies are considering the extent to which wind power can serve as a viable and sustainable alternative to fossil fuels, and are already determining how to encourage wider use at all levels.

Historically farmers and millers were the chief users of wind power - for irrigation and grain milling respectively - and this trend carried on with farmers and others in isolated communities being foremost among the early users of solar panels for jackerywindmills to provide electricity. Recent advances in technology have led to the appearance of large-scale wind farms, and it is these that governments are looking at as a solution to problems with increasing energy prices and climate change. There may be debate as to the extent of human involvement in the latter, but for now most governments are set on reducing reliance on fossil fuels so the issues surrounding wind power must be considered.

I often think that it would be nice to start saving, because lately I have too much spending, including electricity bills. It seems to me that solar energy is a great solution as an alternative. I thought about it when I read about off grid solar systems and now I'm really thinking about buying solar panels for a solar installation.
