 We explain why clean energy is a reliable energy source, or is it? Clean energy is energy that is produced through methods that do not release greenhouse gases or any other pollutants The main sources of clean energy are wind energy, solar power and hydroelectric power In addition, energy that comes from geothermal power, biomass, biofuels and nuclear power are also deemed by some as quite clean in comparison to energy derived from fossil fuels However, let's focus on the cleanest of these energy sources Energy that can be generated from renewable sources like solar power, air currents and water Clean energy is reliable because it will always be available. The sun will always shine, the wind will always blow and water will always blow It will not run out like non-renewable sources of energy like natural gas, coal and oil But it will still depend on fluctuating weather conditions Let's consider how reliable each one is Solar power devices can only supply maximum power when exposed to full sunlight Which makes them unreliable at night time in cloudy conditions and in parts of the world where it is dark for long periods in the winter Solar panels are an easy addition to any rooftop or field But solar power is difficult to store because it requires a lot of battery storage The good news is is that this is something scientists are working on all the time Wind power is more reliable in many areas than solar power as turbines can easily be erected offshore However, they can only operate when the wind is blowing above a certain speed Hydroelectric power is created when dams use the natural flow of water to generate energy This method is extremely reliable on a large scale and reliable even in small rivers and streams in wet areas A combination of renewable and non renewable resources is currently being used to meet our needs However, the time will come when fossil fuels run out and renewable energy sources will have to take their place So how reliable is clean energy? While the wind may not consistently blow everywhere. It's almost always blowing somewhere We can apply the same rules to the Sun's rays Clean energy sources will help fight global warming and air pollution more wind farms, solar farms and hydropower plants will help build the infrastructure we need Technology will improve the efficiency of battery storage, solar panels and wind turbines in the future As technology continues to improve, harvesting and storing of power from clean energy sources will increasingly improve too to provide clean and reliable sources of energy
