An interesting statement from a friend of mine, worth saving and relevant to the disproportionate attention given to climate change, given the other woes on this planet being ignored:
The UK Renewables Obligation is supposedly gonna cost us £30bn to put up solar panels and wind turbines.
Oral rehydration salts are, for simplicity’s sake, 10p. Malaria nets are ~£10. So, for that £30bn you could provide nets and ORS to every child on the planet, and replace every light residential bulb in the UK with low-energy ones, and still have money left over for insulation.
