compact fluorescents are lowest in energy use for most houshold applications

When we stop burning fossil fuels to generate electricity, but instead use renewable sources of energy like solar, hydro, wind, wave, tidal, geothermal and biofuel then there will be far fewer greenhouse gas emissions into the atmosphere.
Recycling copper saves fifteen percent of the energy used in producing the same amount from copper ore. Recycled copper has exactly the same qualities as copper from ore, so it can be recycled over and over without any loss. Copper is non renewable, so it is important to conserve it. Energy saved means fewer greenhouse gas emissions from the fossil fuel saved.
They let off fewer emissions into the environment.
There are several benefits of car sharing. Among them are lower parking demand, fewer miles driven, fewer emissions produced, and lower transportation costs.
Diesel fuel produces fewer emissions than conventional oil (advertised as cleaner). However, it is still a nonrenewable resource that WILL run out in the measurable future. Also, just because it pollutes less does not mean that diesel pollution does not exist.
Deforestation is when a lot of trees are cut down and forests start to disappear. Wood scraps on the forest floor rot and release carbon dioxide (CO2) or methane. With fewer trees in the world they can't remove the CO2 from the atmosphere. So, with fewer trees there is more CO2 in the air and the greenhouse effect is worse.
Fewer cars entering central London- lower pollution emissions Higher usage of public transport- less emissions Will lead to more sustainable forms of transport- walking, cycling etc. Will ease traffic congestion
A environmentally friendly car is a car which produces fewer CO2 emissions than normal cars or that the car doesn't run on gas!
