When coal and oil are burnt to generate electricity, they are converted almost entirely to greenhouse gases. When natural gas is burnt to generate electricity, some of it is converted to water and some is converted to carbon dioxide, a greenhouse gas. Because of this, natural gas is preferable as a fuel, compared to coal and oil. Generating electricity from wind, water flow (hydro-electricity), solar energy and hot rocks (geothermal electricity) emits no greenhouse gases.
Pollution and oil spillsBurning fossil fuels releasing greenhouse gases.
Greenhouse gases started millions of years ago, before life began on earth. They keep the planet warm enough for life, through the natural carbon and water cycles of the planet. Man began producing greenhouse gases about 260 years ago, at the start of the Industrial Revolution, when we dug up and burned coal and oil for industry, transport, and later, for the generation of electricity. These fossil fuels are releasing extra greenhouse gas which is now overwhelming the natural carbon cycle.

No, carbon dioxide (CO2) is NOT an effect of the greenhouse effect. It is one of the causes. With other greenhouse gases it is responsible for the natural greenhouse effect, and the extra levels of CO2 from burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, are causing the enhanced (or accelerated) greenhouse effect which is why global warming is happening.
No, there is a natural greenhouse effect which has kept the earth warm for millions of years. By burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, humans are causing the enhanced (or accelerated) greenhouse effect which is causing global warming.
Greenhouse gases will increase as long as we keep burning fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide, the greenhouse gas causing global warming.
Carbon dioxide and methane. Human activity is releasing more and more of these gases from the burning of fossil fuels (coal, oil and natural gas) and deforestation (cutting down trees which previously removed carbon dioxide (CO2) from the atmosphere).So the natural greenhouse effect that has kept the earth warm for millions of years is being enhanced into an accelerated greenhouse effect.
Electricity is only indirectly related to the greenhouse effect since it is not a greenhouse gas, however, a lot of electric generation is done by burning fossil fuels, which of course does release carbon dioxide, the main greenhouse gas. Any use of electricity has what can be called a "carbon footprint". Of course, that is also true of everything that human beings do. Everything has some degree of impact on global carbon dioxide levels; even breathing releases carbon dioxide.
Humans create greenhouse gases by burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2). Cattle rearing and rice paddy fields release methane (CH4), another greenhouse gas. Natural causes of greenhouse gases are volcano eruptions, and the rotting of any organic matter (trees, plants and animals).
The natural greenhouse effect keeps the planet comfortably warm, warm enough for life. Now, however, by burning fossil fuels (coal, oil and natural gas) in industry, transport and to make electricity, we are adding additional greenhouse gas to the atmosphere. This is producing an enhanced (or accelerated) greenhouse effect which is causing global warming. This is why we should care and try to stop it.
