Why do we need alternatives to fossil fuels?
Renewable energy can play an important role in U.S. energy security and in reducing greenhouse gas emissions. Using renewable energy can help to reduce energy imports and reduce fossil fuel use, which is the largest source of U.S. carbon dioxide emissions.
Why do we need to use alternative sources of energy?
Alternative energy sources are important for two reasons: conventional fuels are finite and will eventually run out, and alternative sources provide energy without adding to the amount of greenhouse gases (GHG) that are accumulating in the atmosphere.
How can alternative energy replace fossil fuels?
Biomass energy Biomass can be burned to create heat (known as thermal conversion), converted directly into electricity, or processed into biofuel. This energy source is cheap, renewable, and reduces the reliance on fossil fuels, but is not considered a clean energy source.
Why is it important to find alternative sources of energy what would happen if all the coil and oil were used up?
1 Answer. Fossil fuels are a limited resource. The deposits of coal, natural gas and oil will eventually run out. Alternative sources of energy will be needed to meet future energy needs.
Should we replace fossil fuels with renewable energy?
Renewables can effectively replace fossil fuels, creating crucial environmental, social and economic benefits. Global dependence on oil, natural gas and coal–and the damage this dependence inflicts–is well documented. But a transition away from fossil fuels is in progress and simply needs to be expedited.
Can alternative energy replace fossil fuels pros and cons?
Pros: It is abundant, and can be used without interruption, cleaner than fossil fuel. Cons: Can result in air pollution, takes a lot of energy to produce, can be seasonable and competes with food production.
What is the alternative to fossil fuels?
Solar, wind, and nuclear power are all alternative forms of energy. Oil and gas dominate the global market but alternate forms of energy are gaining ground as research and development into cleaner energies continue. Nuclear power is less expensive than other forms of “green” energy like hydropower or solar.
Can alternate energy replace fossil fuels?
The short answer: yes. The big question: when? A full transition from fossil fuels to renewable, clean energy will not happen overnight, but the need is growing more urgent.
How can alternative energy can effectively replace fossil fuels?
Biomass energy is another viable source of energy that causes significantly less damage to the environment than fossil fuels. Energy crops are grown for this specific purpose, and the most common biomass materials come from wood, animals, and plants.
What are the advantages of using alternative fuels?
Whether produced via conventional or renewable methods, the advantages of natural gas as an alternative fuel include its domestic availability, established distribution network, relatively low cost, and emissions benefits.
Why the use of alternative energy is beneficial and economical?
Environmental and economic benefits of using renewable energy include: Generating energy that produces no greenhouse gas emissions from fossil fuels and reduces some types of air pollution. Diversifying energy supply and reducing dependence on imported fuels.
Why we should find the alternative of carbon as a source of fuel?
Alternative energy sources have a much lower carbon footprint than natural gas, coal, and other fossil fuels. Switching to renewable energy sources to produce electricity will help the planet by slowing and reversing climate change.
