Wind power, or the lack of it.

All fine and dandy when the wind blows, but in freezing cold weather like now, which is invariably accompanied by still windless conditions, it is currently only capable of providing us with 3% of the power we need gridwatch.co.uk/ .

If we are going to be carbon neutral in the next few decades, we need to reduce our reliance on wind power and develop other more reliable sources of carbon neutral power production; hydro power, tidal and wave power. These sources of power are all running commercially on a small scale in this country, but we should be focussing on these sources of power that come far closer to running 24/7 in all weathers than wind power can possibly do.

Dutch trains now run entirely on wind energy. Why do we spend so much hot air on resisting innovation, and so little money on actually exploiting sources of power?

Water wheels are a great idea.

Sadly, there is no such thing as perpetual motion.

Nothing new under the sun, traditional water wheels need a lot of infrastructure to produce usable power, if you look at the old mills on our rivers the cost or replicating everything would be prohibitive. The cost of solar panels or small wind turbines to produce the same power is far less

If you have a stream flowing past your front door a water wheel is much more efficient than a wind turbine a few fields away.

Every little helps, as the supermarket says.
