Renewable energy are energy sources which are sustainable, as contrary to energy powered by fossil fuels, it will not run out. Renewable energy is brilliant for the environment because not only is it a sustainable source of energy, it is clean too! by clean I mean that its rate of carbon emissions is close to zero compared to that of fossil fuels.
Currently the world is predominantly powered through energy sources which derive from the burning of fossil fuels. This means that there are extreme rates of carbon emissions due to energy deriving from fossil fuel concentrated companies. It is therefore extremely important that we do shift from the usage of fossil fuels to cleaner renewable sources as way of saving our planet who is in desperate need of our saviour.
The effects of carbon emissions add to the greenhouse gas effect. The greenhouse gas effect causes the warming of the earth and increases climate change. With global warming and climate change come catastrophic weather conditions and natural disasters. Cutting down on carbon emissions clearly needs to be dealt with urgently. Since the high rates of carbon emissions are from these fossil fuel companies, what better way to save the climate (gradually) by shifting to renewable resources.
Solar energy, wind energy, micro hydro systems, hybrid systems, fuel cells, nuclear energy, solar panels, solar hot water, solar pumping and battery chargers are all opyions of cleaner energy sources. These energy sources rely on heat from the sun, wind, water, nuclear and also includes a combination of clean and ‘dirty’ energy sources (hybrid systems.) While renewable energy is plentiful, most of the environmental impact is related to the production of the actual equipment used for the energy, but hs minimal enviromental impacts and is definitely a better option.
- Solar energy is the most abundant energy resource on earth — 173,000 terawatts of solar energy strikes the Earth continuously. That’s more than 10,000 times the world’s total energy use. We can definitely rely on this source!
- Human civilizations have harnessed wind power for thousands of years. Early forms of windmills used wind to crush grain or pump water. Now, modern wind turbines use the wind to create electricity.
- Offshore wind represents a major opportunity to provide power to highly populated coastal cities.
- Hydropower is one of the oldest power sources on the planet, generating power when flowing water spins a wheel or turbine.
Some hydropower facilities can quickly go from zero power to maximum output, making them ideal for meeting sudden changes in demand for electricity. Because hydropower plants can dispatch power to the grid immediately, they provide essential back-up power during major electricity disruptions
