2008年の全世界の総発電量は20,261TWh(テラワット時、20,260,838GWh)であった。 これは地球が太陽から1時間に受けるエネルギー(174,000TWh)の11%に相当する。 電力源の内訳は67%は化石燃料、18%は再生可能エネルギー*、13%は原子力による。化石燃料の大半は石炭と天然ガスであり、石油は5.5%。 再生可能エネルギーは大半が水力(92%)で次いで風力(6%)、地熱(1.8%)、太陽光発電は再生可能エネルギーの0.3%で、総発電量の0.06%であった。数値はIEA/OECDより[1] これらの燃料の中には電力以外に熱源、動力源として消費されるものもあるがここでは電力源のみを考慮している。
The Production/Consumption of electricity in year 2008 was 20,261TWh which was 11% of solar energy the earth receive in one hour (174,000TWh). Sources of Electricity were Fossil Fuel 67%, Renewable Energy 18% and Nuclear Power 13%. Majority of Fossil Fuel usage for the generation of electricity were of Coal and Gas, Oil was only 5.5%. 92% of renewable energy was from Hydroelectric followed by Wind 6% and Geothermal 1.8%. Solar Photovoltaic was 0.06%, Solar Thermal was 0.004%. Data are from IEA/OECD (2008)[1][2]
全世界で2008年に発電の為に消費された火力、原子力、水力、その他の総エネルギーは石油換算(ktoe)で4,398,768キロトンで生産されたのは1,735,579キロトン相当の電力であった。発電効率は39%。残りの61%の一部(3%)はコージェネの熱源として利用されたが大半は排出された。ちなみに、発電およびコージェネに消費されたエネルギーは全世界の総エネルギーの36%であった。IEA 2008 Energy Balance for Worldより
Total Energy consumed for the generation of electricity was 4,398,768 ktoe(kilo ton of oil equivalent). Electricity Output was 1,735,579 ktoe, efficiency was 39%, balance of 61% was heat generated. small part(145,141 ktoe, which is 3% of input total) of heat was utilized at co-generation heat and power plants.

全世界で2008年に火力、原子力、水力、コージェネレー・プラント、その他の発電所で消費された総エネルギーは石油換算(ktoe)で4,398,768キロトンであった。 これは全世界の一次エネルギー供給量(TPES)の36%であった。 生産された電力はグロスで1,735,579キロトン相当の電力(20,185TWh)であった。 発電効率は39%。残りの61%の一部(3%)はコージェネの熱源として利用されたが大半は排出された。 また289,681キロトン相当の電力(発電量の17%)は発電所での内部消費と送電ロスで消費され、最終的に消費者へは1,446,285キロトン相当の電力(16,430TWh)が供給された。 これは発電に投入されたエネルギーの33%であった。
Total Energy consumed at all power pants for the generation of electricity was 4,398,768 ktoe(kilo ton of oil equivalent) which was 36% of total primary energy source(TPES) of year 2008. Electricity Output (gross) was 1,735,579 ktoe (20,185TWh), efficiency was 39%, balance of 61% was heat generated. Small part(145,141 ktoe, which was 3% of input total) of heat was utilized at co-generation heat and power plants. There were in-house consumption of electricity and power transmission loss of 289,681 ktoe. Supply to the final consumer was 1,445,285 ktoe (16,430 TWh) which was 33% of total energy consumed.
