Renewable energy is important for the progress of the human race as non-renewable sources will eventually be running out. Coal pollutes the environment creating greenhouse gases and is not a renewable resource. In an event of a nuclear spill, contamination can last for hundreds of years. In many big cities, petrol-fuelled vehicles emit dangerous toxic gases. Today in countries such as Iceland, Taj
ikistan, Paraguay, Albania and Lesotho 100 % of all energy generated comes from renewable sources. However, in most countries, the percentage of power generated from renewable sources is a lot less. Most of the vehicles produced today are not electrically powered. Unfortunately, most motorists still prefer fuel-powered cars and motorbikes that pollute the atmosphere. Renewable energy will reduce greenhouse gases and fuel emissions.
