Harnessing “nature’s power” to form a clean energy revolution. Here’s everything you need to know about energy renewables and how we can change the way our nation is powered.
What Is Renewable Energy?
Energy Renewables are generated from naturally replenishing sources like sunlight and wind, whereas the energy from renewable sources can transfer to mechanical movement, heating, and electricity generation. Fossil fuels, coal, oil, and gas, to the contrary, are non-renewable energy sources that are produced using resources that are limited and may eventually run out.
The use of renewable energy has existed since the beginning of time. If we go back in time to our prehistoric ancestors, they used various methods of effectively harnessing energy sources that have played a central role in human development. For instance, people awoke and slept with the light, relied on the sun for warmth and energy, burned wood and dung for heat, and water power to build basic mills. Renewable resources are often seen as futuristic technology, but they are also a technology of the past. Currently, the past technology has been modernized and developed, harnessing nature’s power to form a clean energy future, making it smarter, more secure, and better integrated.
TYPES OF RENEWABLE ENERGY SOURCES
Solar Energy
Did you know that about 173,000 terawatts of solar energy strike the Earth every second? Interesting fact is that it is more than 10,000 times the world’s total energy needs. Clearly solar is the most abundant source of Energy on earth.
Solar technologies are capable of generating electricity through solar power, to produce solar thermal energy for power generation, initiate solar architecture to clean and renew solar power and produce fuels for a wide range of applications. Also Solar energy is a key solution in battling the current global warming and reducing our dependence on nonrenewable energy resources like fossil fuels, which has the greatest impact on the climate crisis.
Wind Energy
Wind energy offers numerous advantages, which is why it is one of the world's booming energy sources. From old-fashioned windmills, the wind power industry has advanced from traditional windmills to inventing turbines as tall as skyscrapers which convert wind energy into rotation of the blades, which powers an alternator to produce electricity.
Other Alternative Energy Sources
Hydroelectric Power
Hydroelectric power is the largest renewable energy source for electricity in the world representing around 16% of global power production. Whereas in Sri Lanka Hydropower is well developed and modernized and will continue to play an important role in the island’s energy grid.
Biomass Energy
"Organic material" is the simplest definition of biomass. By extension, it indicates that it originates from anything that is or has ever been living, including animal waste, agricultural waste, garden waste, and so on. The fact that biomass is renewable and has a seemingly endless supply makes it particularly advantageous.
Ocean
The ocean covers 70% of the world’s surface, and it is one of the planet’s most abundant sources of renewable energy. Because ocean wave power can be captured and transformed into clean electricity sufficient to power the whole world.
Geothermal Energy
Did you know that the Earth's core is extremely heated and that this heat may produce energy? It is the heat that is generated within the Earth that is referred to as geothermal energy. It is a resource that can be gathered for human use and is accessible wherever on the surface of the Earth.
Why Solar Energy?
Limitless Solar Energy - Solar Energy relies on the sun as its main source.
The sun is a magnificent renewable resource that has all the power to sow the seeds of life on earth and deliver clean, sustainable energy to all living beings. In fact studies show that more energy from the sun reaches earth in one hour than is used by the entire population of the world in one year. More importantly, the sun shines all over the world making solar power viable anywhere.
Solar Energy uses simple technology and has no moving parts hence they last a long time.
Solar Energy is highly reliable with a long service life of 25+ years of guaranteed electricity and it can continue producing electricity for many many years after that.
Solar Energy is a clean renewable energy resource
Solar energy is a clean, renewable energy source with no greenhouse gas emissions and low overhead expenses
Avoid High Utility Expenses
Solar energy may be a helpful hand in these unprecedented times where inflation is on the rise, the cost of living is growing daily, and there are regular power outages caused by the dollar crisis. You can avoid excessive utility costs by using stored solar energy.
Solar Energy Is The Key Solution To Power The Nation
Our nation is now dealing with a severe energy crisis, primarily on account of a lack of foreign currency to import diesel and other fossil fuels required to produce energy. We rely on thermal energy as our main source of energy generation because our hydropower-producing capability can only supply roughly 30% of our entire energy needs.
The earth obtains enough solar energy—sufficient to satisfy the entire energy needs of the world for a whole year. In contrast, Sri Lanka is in the most privileged position of being a tropical paradise with over 250 days of bright sunshine annually anywhere in the country where Solar energy would not only make electricity greener and affordable but will improve Sri Lanka’s economic competitiveness as well.
The renewable energy sector is evolving quickly as a result of its unprecedented growth, whereas the solar sector is experiencing significant cost reductions that are enabling technological advancement and market expansion and leading to a significant increase in the supply, integration, and distribution of solar energy across the globe.
