Energy saving tips

light-bulbs
thermostats
air-conditioning

free energy
solar
wind-turbine
coal - probably the most environment-unfriendly method of producing energy because it release CO2 most.
tidal
heat
hydro
geothermal
biomass
fossil-fuel
biofuel (may not be good for the environment because it burn and produce CO2 perhaps)
fuel-cells
natural-gas - Natural gas is not necessarily good for the environment because it burns and produce C02. Also, accidental gas pipe leak cause fire / explosion. This is a hazard for both homeowners and the public.

What is the most environment-friendly method for producing energy?

Residential solar and wind are probably the most environment-friendly method for producing energy. Large commercial solar power plants are known to kill birds and ground animals. Hydro and tidal may have impact on fishes. Other techniques for producing energy may release CO2 which contribute to global warming.
