Wind farms and photovoltaic cells

Wind farms are very controversial. They are large. Some consider them as eyesores - which they are if they are built on a commercially viable scale. But something has to be done to produce electricity in an environmentally acceptable way.

The answer is with photovoltaic cells. These are units which can be fitted on the roof - possibly even replacing tiles in new houses - which generate electricity silently and with no moving parts during the hours of daylight. This electricity is stored in special batteries. Surplus electricity can be sold back to the electricity companies.

There are many people who are keen to take advantage of this option. The Government supports it. The fly in the ointment is the planners!

When will the planners catch up with the fact that we must start creating our own electricity? It isn't an option any more. It's a necessity.

Photovoltaic cells could be placed on the millions of acres of rooftops. What isn't used by the occupier could automatically be sold back to the network.

The advantages of the photovoltaic method of producing electricity are massive.

Firstly there is the reduction in the need for large power stations. Once the technology is established and developed to its full potential it would solve the problem of the climate endangering coal-fired power stations in developing countries. And increased production of the cells would reduce the cost.

Secondly it would provide a nice little extra income and also keep you safe from power outages in bad weather.

Photovoltaic cells work when exposed to light. Even in winter we have daytime!

Storage of electricity produced this way is improving all the time. The more take-up there is of this technology the better it will get. It will also get less expensive.

If you would seriously like to consider using photovoltaic cells you should read this book.
