Renewable energies are ideal alternatives to using carbon-based fuels. They do not contribute to causing greenhouse gases, climate change and global warming. Generated using the power of nature, they are clean and they quickly replenish without having an impact on the environment.
The main forms of renewable energy:
- Wind power: generated using the force of the wind.
- Solar power: generated using sunlight, by means of solar panels.
- Hydropower: generated using the water currents of rivers and estuaries.
- Bioenergy: generated using sustainable biomass – natural organic material.
- Tidal energy: generated using the movement of sea and ocean waves.
- Geothermal energy: obtained from the natural heat of the Earth.
The 8 main benefits of renewables:
- They do not pollute, they are clean and their environmental impact is very limited.
- They help care for and conserve the environment and natural resources.
- They are unlimited and natural.
- They reduce the problems derived from burning fossil fuels, such as greenhouse gases (for example, carbon dioxide) and the resultant global warming or climate change.
- They support the economic development of local economies, which generates employment.
- They encourage energy efficiency and sustainable development.
- They promote a better quality of life.
- They are the best option and alternative to conventional non-renewable and polluting energies, such as coal, oil, gas and nuclear energy, which represent 80% of the world’s energy sources.
The main problem with renewable energy sources is the high level of initial investment. Energy storage, technological development and land-use costs can also make it difficult to plan the infrastructures necessary to use renewables, especially in developing countries.
Renewable energies are clean and natural. They are the future – and everyone must start promoting them for sustainable development.
