why do we use fossil fuels instead of renewable energy

No matter the drawbacks of renewable energy or benefits of fossil fuels, one aspect ultimately trumps the argument: fossil fuels are non-renewable. Fossil fuel consumption as doubled every two decades throughout the 20th century, with no signs of abating. Predictions for final depletion of fossil fuel reserves range from 50 to less than 150 years. Petroleum in particular presents a challenge as a resource: not only does demand consume oil as fuel but also as raw material for plastics, solvents, fertilizers, pesticides and other petrochemicals. Businesses can make an immediate impact by modifying their consumption habits. Building improvements, equipment upgrades, and simply turning off power when not in use impacts the bottom line beyond lower monthly utility bills. It can extend the life cycle and lower the ongoing maintenance costs of equipment, and it can lower exposure to the risk of energy price spikes and environmental or legal costs.
All life on earth is sustained by energy from the sun.

Plants and animals can store energy and some of this energy remains with them when they die. It is the remains of these ancient animals and plants that make up fossil fuel Fuels such as coal, gas and oil which are mined from the earth and burned to produce energy. They are formed from broken down animals and plants that died a very long time ago. non-renewable A resource that cannot be replaced when it is used up, such as oil, natural gas or coal. because they will run out one day. Burning fossil fuels generates greenhouse gas Naturally occurring gases in the atmosphere such carbon dioxide, methane and nitrous oxide. They are believed to have increased through burning more oil, petrol, and coal. unsustainable Resources which cannot be used forever and cannot be replaced or recycled after they are used.

The use of fossil fuels is unsustainable for example. Hence the need to find more renewable, sustainable ways of generating energy. Renewable or infinite energy resources are sources of power that quickly replenish themselves and can be used again and again. Some resources can be thought of as both renewable and non-renewable. Wood can be used for fuel and is renewable if trees are replanted. Biomass, which is material from living things, can be renewable if plants are replanted. How long will fossil fuels last? Estimates from international organisations suggest that if the world's demand for energy from fossil fuels continues at the present rate that oil and gas reserves may run out within some of our lifetimes. Coal is expected to last longer.
