What is the best energy source for the environment and what happens to Earth without fossil fuels?
Generating renewable energy creates far lower emissions than burning fossil fuels. Transitioning from fossil fuels, which currently account for the lion's share of emissions, to renewable energy is key to addressing the climate crisis. The sun is the main source of energy on Earth. Other energy sources include coal, geothermal energy, wind energy, biomass, petrol, nuclear energy, and many more. Energy is classified into various types based on sustainability as renewable sources of energy and non-renewable sources of energy. In most ecosystems, the ultimate source of all energy is the sun. Nuclear is a zero-emission clean energy source. It generates power through fission, which is the process of splitting uranium atoms to produce energy. The heat released by fission is used to create steam that spins a turbine to generate electricity without the harmful byproducts emitted by fossil fuels. Petrol, diesel, and kerosene are petroleum products and they produce pollutants like carbon-dioxide and smoke. CNG or compressed natural gas is a smoke-free gas and does not spread pollution, and thus used in our vehicles. Therefore, CNG is considered as an eco-friendly fuel. Green energy is that energy which does not pollute the environment and is renewable in nature. The energy sources such as sunlight, wind, rain, tides, etc. can be called as green energy. This is because these are readily available on Earth, can be naturally replenished and do not even harm the environment much. In a world without fossil fuels, the sun might be used for cooking or heating homes and water, but as an energy source for industry it's probably not viable. That leaves wind and water. On the sea, wind powered most trade and exploration until well into the 19th century. Without electricity, there would be no cash machines, no lifts, no power to keep the factories going, and no petrol pumps. Ventilators and medical treatment machines will stop working, putting patients in critical conditions throughout the hospital.
