Climate change seems to be the buzz word now.
Windmills are not a popular source of electricity. For the amount of space they take up they are not all that effeicient.
Wave power supplied by barrages I'm not too sure about. The seas are extremely powerful elements. A lot can go wrong with storms, tsunamis, rising sea levels, freak waves and storms to
name just a few potential problems.
Coal, gas and oil fired power stations are very polluting even in their most efficient forms.
Atomic energy seems to me to be a solution of desperation and lack of foresight. We still haven't worked out a really successful way of dealing with the radioactive waste we have already. There is only a limited amount we can safely bury no matter what sort of protective casing we use.
All the time we are ignoring the one unlimited source of power that has been here since the solar system came into being. Every day enough power comes in the form of solar power to solve all our problems for ever.
Even with our present knowledge we could re-roof every building with photovoltaic cells providing power for homes and for a large part of the commercial needs of the world.
Back up power could be used if necessary using two-way meters, but it is more than likely that this would not be needed.
Contrary to what most people understand, you do not need bright sunlight to operate solar panels. all they need is light.
The electricity is collected in batteries. In the early days these were large and cumbersome but they are getting smaller and more efficient as new systems are developed.
If we are sincere in our desire to save the planet as a place where human life can continue we have to be willing to learn new things and get into new habits. If that involves installing roof systems and learning how to use batteries and a new metering system - so be it.
Would it be possible for the power to flow directly to a collecting point?
If we put our minds and finances to working on this I see no reason why fossils fuels for any sort of power should be things of the past.
