How does alternative energy reduce pollution and how does the use of alternative energy sources help to prevent the effects of climate change?
Traditional energy sources, like coal and oil, rely on combustion which releases harmful pollutants and greenhouse gases like carbon dioxide into the atmosphere. These pollutants contribute to smog, acid rain, and respiratory problems. They also trap heat in the atmosphere, causing global warming and climate change.
Alternative energy sources, on the other hand, offer a cleaner solution:
- Reduced Pollution: Unlike fossil fuels, renewable energy sources like wind, solar, geothermal, and hydropower don't burn anything to create energy. This significantly reduces air and water pollution. Even bioenergy, which burns organic matter, generally produces fewer emissions than fossil fuels.
- Combating Climate Change: By not emitting greenhouse gases during energy production, alternative energy sources help mitigate climate change. As we transition from fossil fuels to renewables, the overall emission of heat-trapping gases goes down, slowing down the pace of global warming.
While some aspects of renewable energy, like manufacturing solar panels, may create minor environmental impacts, they are generally much smaller compared to the constant pollution from traditional sources.
In essence, alternative energy offers a path towards a cleaner future with less air and water pollution, and a more stable climate.
If you look at it from a different perspective, then you will realize a very serious problem that is looming over our heads and has the potential to destroy the planet. Energy usage has increased sharply since around 1960 worldwide due to modernization and development. A major portion of the energy demand is met by using the fossil fuel. It has cascading effects. Global warming and carbon space depletion at a rapid pace are the direct result of that. In the next 100 years or so we will exhaust all the known fossil fuel reserves while the energy demand will continue to grow at the present rate and maybe more. Depletion of carbon space will not give even 100 years to drop at a very dangerous level of oxygen concentration in the air causing extreme difficulties in breathing. Energy in any form that will not cause these two effects will help mankind sustain its growth and development and will be helpful. Renewables cannot meet the whole demand as it stands now. Hydrogen energy is in its infancy today. Maybe policymakers will be debating about the usage of nuclear power for power generation in the next century.
Renewable energy sources which are available in abundance all around us, provided by the sun, wind, water, waste, and heat from the Earth are replenished by nature and emit little to no greenhouse gases or pollutants into the air. 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. As two of the cleanest sources of energy currently available, switching to wind and solar power can limit PM2. 5 levels almost immediately. Other renewable energy sources, like geothermal, still emit some PM2. 5 but significantly less than fossil fuels. Overall, clean energy is considered better for the environment than traditional fossil-fuel–based resources, generally resulting in less air and water pollution than combustible fuels, such as coal, natural gas, and petroleum oil. Alternative energy here includes hydroelectric energy, solar energy, geothermal energy, wind energy, nuclear energy, and biomass energy. There is no path to protecting the climate without dramatically changing how we produce and use electricity: nearly 40% of US CO2 pollution comes from power plants burning fossil fuels. But we can turn things around. Renewable energy minimizes carbon pollution and has a much lower impact on our environment. Generating electricity and heat by burning fossil fuels – coal, oil, or gas – causes a large chunk of the greenhouse gases, such as carbon dioxide and nitrous oxide that blanket the Earth and trap the sun's heat. Increased use of fossil fuels without actions to mitigate greenhouse gases will have global climate change implications. Energy efficiency and increase use of renewable contribute to climate change mitigation and disaster risk reduction. Growing plants absorbs CO2; burning plants releases CO2. The total impact on CO2 in the atmosphere depends on how sustainably the bioenergy is produced. Nuclear energy is carbon-free: a nuclear power plant does not emit any CO2, or any other greenhouse gases. Renewable energy sources which do not deplete and are scarcely used by the population are called non - conventional sources of energy which do not cause environmental pollution.
