In 2005 the World Energy Council estimated the world's generating capacity from biomass to be at least 40 GW per year, larger than that from any other renewable resource except for wind and hydropower [1].
This article provides an in-depth review on the wind, hydropower, geothermal and nuclear energy options in Nigeria, for a sustainable development of its power sector.
The IEA has said: "Photovoltaic and solar-thermal plants may meet most of the world's demand for electricity by 2060 -- and half of all energy needs -- with wind, hydropower and biomass plants supplying much of the remaining generation".
Fuel economy for new U.S. vehicles was assumed to increase 30percentt by 2030; the global share of energy from "renewables" (solar, wind, hydropower, biomass) would quadruple, to 8percentt.
Africa has some of the world's best potential sites for wind, solar and hydropower.
The trigger prices for various renewable energy sources are $74 for geothermal, $116 for wind, $173 for hydropower, and $194 for solar.
Empirical data from the Swedish TGC system for wind power, biopower, and hydropower are used for this analysis.
It also extends the credits for wind, biomass, geothermal, small irrigation, hydropower, landfill gas and ocean currents for three years, to the end of 2012.
The mechanical source of power is usually transformed into electricity at high efficiency rates, e.g. 35% for wind or 70 90% for hydropower.
Junda Lin of the China Greentech Initiative points out that the 2020 target for nuclear has to be seen in the context of a 200GW target for wind and an extra 100GW of hydropower.
