How the alternative energy resources can fulfill our future energy demand?
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 .
Is alternative energy sustainable?
The main advantage of renewable energy is that – by its very definition – it’s sustainable . Each type uses natural resources that can be replenished as we move forwards. Other benefits include little to no waste or carbon footprint, economic improvements and less overall maintenance.
Why alternative energy is bad?
The most negative impact of this giant among the renewables is the flooding of an area . When the water stored within the dam is released all at once, it can cause the river downstream to suddenly flood. This can result in the destruction of agricultural land, forest, wildlife, and land.
How will renewable energy impact the future?
Renewable energy could power the world by 2050 . Here’s what that future might look like. Switching to renewable energy could prevent 4 to 7 million deaths from air pollution annually worldwide. It’s possible to switch to a fully sustainable global energy landscape within the next 30 years, according to research.
How does renewable energy benefit the environment?
Renewable energy is no exception to the rule, and each source has its own trade-offs. However, the advantages over the devastating impacts of fossil fuels are undeniable: from the reduction of water and land use , less air and water pollution, less wildlife and habitat loss, to no or lower greenhouse gas emissions.
What is conclusion example?
For example, if you write a paper about zoo animals, each paragraph would probably be about one particular animal. In your conclusion, you should briefly mention each animal again . “Zoo animals like polar bears, lions, and giraffes are amazing creatures.” Leave your readers with something to think about.
