Solar Energy
Solar energy is a form of renewable energy.
Energy aplenty from solar PV
The future for solar photovoltaic cells is bright. With wind and tidal power still developing, the efficient PV cells being developed seem sure to absorb more renewable sun-power than before and really push solar energy as a dominant form of energy. This league table will change a lot in the future but several countries are really setting out their store (and grabbing a part of the big market for cells.)
Solar energy saves the earth?
When will people, especially governments, believe those who are far better qualified than they are to judge the earth and its workings. When hell freezes over, perhaps? No, I'm sorry, it's when earth becomes hell, as it already has for the victims of increasing climate change.
