Renewable energy is energy that has been derived from earth’s natural resources that are not finite or exhaustible, such as wind and sunlight. Renewable energy is an alternative to the traditional energy that relies on fossil fuels, and it tends to be much less harmful to the environment. The benefits of renewable energy generating 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, creating economic development and jobs in manufacturing, installation, and more. Due to environment-friendly and less emission of gases from renewable energy, it is considered as sustainable energy which is firmly also supported for the society from each dimension like economic, social and environmental. Renewable energy resources have the ability to complete the world’s energy demand, protect the environment, and provide energy security. Along with the outstanding advantages of these resources, some shortcomings also exist like the variation of output due to seasonal change, which is the common thing for wind and hydroelectric power plants; hence, special design and consideration are required.
Key benefits of renewable energy for people and the planet
Energy sources have an impact on our environment with no exception to the rule, and each source has its own trade-offs. fossils fuel has undeniably caused disadvantages from the reduction of water, land use, less air, pollution of both land sea to wildlife loss, lower greenhouse gas emission and habitat loss. Renewable energy is an important source for power generation shortly because we can use these resources again and again to produce useful energy.
- Renewable energy emits low air pollution: Worldwide increases in fossil fuel-based road transport, industrial activity, and power generation (as well as the open burning of waste in many cities) contribute to elevated levels of air pollution. In many developing countries, the use of charcoal and fuelwood for heating and cooking also contributes to poor indoor air quality. Particles and other air pollutants from fossil fuels literally asphyxiate cities.
- Renewable energy emits no or low greenhouse gases. That’s good for the climate. The combustion of fossil fuels for energy results in a significant amount of greenhouse gas emissions that contribute to global warming. Most sources of renewable energy result in little to no emissions, even when considering the full life cycle of the technologies.
- Renewable energy makes the energy system resilient. That’s important to prevent power shortages. Renewables make urban energy infrastructures more independent from remote sources and grids. Businesses and industries invest in renewable energy to avoid disruptions, including resilience to weather-related impacts of climate change.
- Renewable energy is accessible to all. That’s good for development. In many parts of the world, renewables represent the lowest-cost source of new power generation technology, and costs continue to decline. Especially for cities in the developing world, renewable energy is the only way to expand energy access to all inhabitants, particularly those living in urban slums and informal settlements and in suburban and peri-urban areas.
- 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, creating economic development and jobs in manufacturing, installation, and more.
