Energian kulutus maailmassa

"Industrial users (agriculture, mining, manufacturing, and construction) consume about 37% of the total 15 TW. Personal and commercial transportation consumes 20%; residential heating, lighting, and appliances use 11%; and commercial uses (lighting, heating and cooling of commercial buildings, and provision of water and sewer services) amount to 5% of the total.

The other 27% of the world's energy is lost in energy transmission and generation. In 2005, global electricity consumption equaled 2 TW. The energy used to generate 2 TW of electricity is approximately 5 TW, as the efficiency of a typical existing power plant is around 38%. The new generation of gas-fired plants reaches a substantially higher efficiency of 55%. Coal is the most popular fuel for the world's electricity plants."

Eli 37 % energiasta kuluu teollisuuteen. Enää tarvii eritellä eri teollisuudenalojen käyttämät energiamäärät.

ainut energia jota voidaan moisesti hyödyntää?

mitä sähkö on?

miksi energia voi muuntua yhdestä toiseksi, eikö se tarkoita, että kaikki on yhtä ja samaa, vain mielemme on sen osittanut käsitteisiin joita sen jälkeen enää havaitsee.
