In 2011 Japanese with solar power sold 50 per cent more power to the grid than in 2010. They made $1.2 billion from their surplus electricity.
Nissan now has two energy-efficient cargo ships to transport its LEAF electric vehicles.
The ships have electronically controlled diesel engines and solar electricity that save thousands of tons of CO2 emissions yearly. Sails are next on the agenda for assisting cargo ships.
In the US wave and tidal power can realistically produce 15 per cent of energy needs by 2030 according to the Dept of Energy.
Last year was the ninth warmest since 1880. The highest annual average global surface temperature so far occurred in 2010. Around the world many food crops are affected by rising temperatures. Wheat will be particularly vulnerable according to a Stanford University scientist. He observed on satellite images that when the heat ramps up the wheat turns brown and stops growing.
