With rising demands for scarce fossil-based energy resources and the consequent greenhouse emissions, there is a growing effort to fulfil our energy demands with cleaner, greener alternatives.
An important reason as to why is because renewable energy is better for the environment.
Fuel-free, carbon-free electricity generation has numerous advantages.
However, despite their current volatility, the general cost pattern for fossil fuels is in the other direction.Growth of green and clean energy is inevitable, as figures from the International Energy Agency (IEA) show: they accounted for nearly 50% of all new power generation capacity built-in 2014, making them the second-largest energy source in the world after coal.As per the reports from the International Energy Agency, global electricity demand would climb by 70% by 2040, with its percentage of final energy usage jumping from 18 to 24% over that period, majorly owing to the developing economies such as India, Africa, the Middle East, China, and Southeast Asia.Why Do We Need Alternative Energy Sources?There are two reasons why you should adopt renewable resources: they are infinite (especially solar energy), and they do not give off toxic substances like carbon monoxide dioxide (CO) and greenhouse gases (GHGs).We must understand that finite energy sources are limited resources, implying that we should spend them wisely.
And, as deposits become scarcer, drawing them would become extremely high-priced much before this time.Moreover, given the current situation of the globe, drying out of fossil fuels is not our primary concern; instead, the emissions produced by burning them are far more dangerous.Kinds of Renewable EnergyRenewable energies cover:Wind energy: the energy taken from the wind.Solar energy: refers to the energy derived from the sun.Hydraulic energy: refers to the power or energy received from waterways.Biogas and biomass: refer to the energy extracted from organic material.Geothermal energy: refers to the heat energy from the core of the Earth.Tidal energy: refers to the power or energy gained from the tides.Wave energy: the energy taken from ocean waves.Bioethanol: the organic fuel fit for vehicles and collected from the fermentation of vegetation.Biodiesel: organic fuel for automobiles, obtained from vegetable oilsWhat Are the Advantages of Using Renewable Energy?You may also hear the renewable sources of energy referred to as green energy or clean energy.
It is far friendlier for the planet to obtain electricity from renewable energy sources than to burn fossil fuels.By pursuing alternative energy sources, both governments and private customers can significantly reduce their carbon footprint.
