I expect that, as oil is depleted and oil prices rise, the attempt to ban solar power in all forms will pick up speed. There will be many excuses given such as:
1. Wind turbines kill migratory birds.
2. Sea Solare Power plants will upset the thermal structure of the oceans.
3. Solar panels on homes will constituted fire hazards.
4. Removal of flammable brush from forest floors will upset the local ecology.
5. Solar panels (photovoltaic or thermal) on homes are aesthetically undesirable.
And so on....

The REAL reasons will be, of course, a combination of ever-present stupidity plus the interest in maintaining ever higher fuel prices for the fuel companies. Look how much money they made in the recent fuel shortage. Shortages are GOOD for suppliers.

many sunny California cities largely ban solar panels through bizarre zoning requirements - we realize that California ought to recall a lot more than their Governor. They are wasting time on zoning solar panels out of existence while the state and most local governments go bankrupt?

Home owners associations: represent one of the largest roadblocks to solar power installations in the domestic market -- the vast majority ban solar power structures and it has been quite hard to get any to relent.

Aesthetics also play a part as people may not want a solar panel sticking out of their roof and some homeowner associations even ban solar systems because of what they consider a not-pleasing addition to a house.

I hope that when the hon. Gentleman speaks in this debate he will clarify his position on the decision of Lewes district council to ban solar power in the town, despite the fact that it was particularly badly affected by flooding.

We also do not contest the fact that many women in rural areas cannot yet afford a well-built, solid, solar box cooker. But is this a reason to ban solar cooking? To categorically declare that the cookers are unacceptable and inappropriate to the needs of the poor? That they cannot be recommended? There are a large number of families who can afford this expense. Many family members, with an average-paid job, buy cookers for their mothers, sisters and relatives in rural areas. International donors often subsidize promotion programmes, and our organization encourages companies and other organizations to distribute cookers on a payment-by-instalment basis.
