He gave a run-down on the development of renewable energy sources to the Maltese press earlier this week, and this is what he said:
"Wind renewable energy is now mature. It could soon be as cheap as fossil fuels. In most coastal areas, wind energy could be as low as €0.05 per kw/hour. This is even cheaper than fossil fuels. 20% of the energy needs in Denmark come from wind energy, 10% in Spain, 8% in Germany and from 3-6% in the EU as a whole."
"In 2009, wind energy produced some 158GWatts in the whole world, which works out at something like 55 power stations compared to the 375 nuclear power stations. But wind stations are increasing by 25% a year. By 2025, energy from wind will overtake energy from nuclear."
"Solar energy produced only some 25GWatts last year, equivalent to four power stations. But it has a 50% growth rate and the costs are falling. Last year in the US solar energy went below the $1 per Watt mark."
"Thermo dynamics create energy through using huge mirrors. Covering just two per cent of the world's deserts by such mirrors would solve all the energy needs of the entire world. The cost is still high but is falling."
Pistorio, a native of Sicily, added: "A Sicilian saying says that the sun that hits one square metre of Sicilian land is the equivalent of one barrel of oil."
