Renewable Energy Global Status Report
record investment in new renewable energy capacity occurred in 2005—$38 billion,up from $30 billion in 2004.Germany and China were the investment leaders,with about $7 billion each,followed by the United States,Spain,Japan,and India.Wind power registered the second highest added capacity,almost as much as large hydropower,with existing capacity growing 24 percent to reach 59 gigawatts (GW).

Wind power was second in power capacity added,with 11.5 GW added and existing capacity growing by 24 percent to reach 59 GW. More than half of global wind power additions were in three countries:the United States (2.4 GW),Germany (1.8 GW),and Spain (1.8 GW).India jumped ahead of Denmark into fourth place in terms of total installed capacity,adding 1.4 GW in 2005.Strong growth took place in China,with 0.5 GW added to the previous existing 0.8 GW.Offshore wind installations grew by at least 180 megawatts (MW).

Solar PV, Existing World Capacity
Grid-connected solar photovoltaic (PV) continued to be the fastest growing power generationtechnology,with a 55 percent increase in cumulative installed capacity to 3.1 GW,up from 2.0 GW in 2004 More than half of the annual global increase occurred in Germany,which saw over 600 MW of PV installed in one year.Grid-connected solar PV increased by about 300 MW in Japan and 70 MW power plant,10 MW total,in Germany,and many 200large commercial installations of tens and hundreds of kilowatts (kW) each.German cumulative PV capacity exceeded Japan’s for the first time. Including off-grid applications,total PV existing worldwide increased to 5.4 GW,up from 4.0 GW in 2004.
Solar Hot Water/Heating Capacity Added in 2005
Solar Hot Water/Heating Capacity Existing in 2005
Existing solar hot water capacity increased by 14 percent to reach 88 gigawatts-thermal (GWth), up from 77 GWth in 2004,excluding unglazed swimming pool heating. Accounting for retirements,13 GWth of new capacity was added in 2005.China installed 80 percent of that new capacity (10.5 GWth) andremained the world leader,with over 60 percent of the global installed capacity. Solar hot water in Europe increased by more than 1.3 GW th. India and several other countries saw an acceleration of solar hot water installations.

World Fuel Ethanol Production
Ethanol production increased to 33 billion liters in 2005,up from 30.5 billion liters in 2004 an 8 percent increase,with most of this in the United States.Fuel ethanol production in the United States caught up to Brazil’s for the first time,growing by 15 percent in 2005,as both remained the dominant producers. Fuel ethanol consumption in Brazil was fairly stable,supplying 41 percent of all motor vehicle fuel (non-diesel) sold,about the same as in 2004.
World Biodiesel Production
Biodiesel growth far outpaced that ofethanol. Global production ofbiodiesel reached 3.9 billion liters,up from 2.1 billion liters in 2004. Biodiesel production increased by 75 percent in the EU,led by increases in Germany,France, Italy,and Poland,and tripled in the United States. Ge rmany alone accounted for halfofglobal bio diesel production in 2005.Nine EU countries began producing biodiesel for the first time in 2005,bring ing to 20 the number of EU biodiesel producers
