How is solar energy renewable

Solar energy is one of the cleanest and most fascinating energy source in the world today. Millions of homes and businesses have solar energy systems capable of harnessing sunlight to generate both electrical and thermal power. Solar energy technology harnesses the sun’s energy and makes it useable. The science is straightforward: more sunlight means more energy generation. It’s clean and renewable energy. Now the question is: how is solar energy renewable?

What is a renewable energy source

A renewable energy source is a source of energy capable of naturally replenishing itself as it is being used.

In other words, you can never run low or run out of renewable energy at any rate of usage.

Unlike non-renewable fossil fuels (coal, natural gas, and oil), which was formed thousands of years ago, solar energy is a renewable resource because it is supplied by the sun every day.

The solar panel in your solar panel system captures solar energy via sunlight, then turns it to usable energy.

Solar panels, aka photovoltaic cells, are found on things like handheld calculators, rooftops, and spacecraft.

The cells consist of semiconductor materials that resemble computer chips. These cells capture sunlight, extract electrons from sunlight, and generate electricity.

Fossil fuels, however, are formed from prehistoric carbon remains inside the Earth’s crust.

Fossil fuel, of course, is dangerous to our environment and is significant in greenhouse gas formation and global climate change.

Fossil fuels draw on finite resources that may ultimately become too costly to recover; renewable energy sources, however, are usually unlimited in availability.

Solar energy is limitless. Limitless solar energy can be explained with the sun providing power that meets and exceeds the energy needs of the whole world.

Hourly, the sun transports more energy onto Earth than it needs to meet global energy needs for an entire year.

So, as long as the sun is shining, solar energy will be around.

According to the people at NASA, the sun is going to burn for another 5 billion years. This means we can still bank on cheap and clean solar energy for many years to come.

How clean is solar polar

Asides being renewable, solar energy is regarded as a “green” energy source. Green in the sense that it is not harmful to the environment.

The fact is, non-renewable fossil fuel releases greenhouse gases, which are dangerous to the atmosphere (as they amplify global warming).

But solar energy systems are entirely zero-emission and clean using just the sun’s rays to meet all your energy needs. This is an environmentally friendly and financially smart method of generating power.

With the growing environmental concerns over the climate change risks of burning fossil fuels, choosing solar energy is selecting a better environment.

Passive and active solar energy systems

You can generate solar energy with basically two systems: Passive and active.

Passive solar energy systems are made without electronic devices—without photovoltaic cells.

The passive mode is often used for heating solutions.

With passive solar energy systems, solar energy is generated by design elements like thermal mass (concrete, tile, and brick), proper insulation, shading, and window location.

Here, windows are placed on the sunny side of the building to generate heat. Passive solar energy systems leverage materials, climate, and your building’s site to lower energy use.

Passive designs are standard in the windows of residential homes where thermal systems are used to convert the sunlight into heating solutions.

Active solar energy systems are combined with external electrical or/and mechanical equipment that changes sunshine into usable energy. They are made with three major parts: storage tanks, panels, and pumps.

Whether you are choosing active or/and solar energy systems, solar energy is entirely renewable.

Our sun is a free resource. For over 4.5 billion years, it has been giving us clean and clean and dependable power.

The future is solar energy.

Solar energy is undoubtedly renewable, and cost-effective.

And it is a reasonable alternative to non-renewable resources which will get exhausted.

When it comes to tapping into the alternative energy market, solar energy can help lower your utility bills while making you more environmentally conscious.

You can significantly reduce your home’s heating and cooling needs by 90 percent.

Zero greenhouse gas emissions mean that you can generate clean energy.

The energy produced is more than you will ever need. You are not burning fuel or buying diesel.

Once you have your solar panels installed, your operating cost is significantly lower than any other type of energy generation system. You can generate large amounts of electricity without the uncertainty and expense of coal-generated power and diesel because you don’t need fuel.

A report says that about 22.5 percent of global energy production will come from renewables in 2020.

As the Middle East’s oil and gas supply becomes more unstable, the world now is shifting to renewable energy. Renewable energy continues to penetrate the market as clean energy technologies, especially solar energy systems, continue to thrive.

It is an unlimited energy source that is not just pollution-free but also noise-free. The versatility of the technology can be used to power electronic devices, buildings, and even cars.

Green and cheap and renewable

Solar energy is as good as it gets. A clean, green source of energy reduces your carbon footprint and contributes to a sustainable future.

Moreover, if you live off-the-grid and cannot use traditional electricity, solar energy can grant you electricity independence.

Unlike your utility bill, the sun will not increase its rates. And with a solar battery storage system installed along with your solar panel, you can store up electricity for even rainy days and nighttime.

Because you are operating energy domestically, you are in control of your energy usage and bills.

Most solar panels are quite durable, built for harsh sunlight and rainfall. And with the durability of solar power systems, there is a less likelihood of service interruption even during natural- or human-caused disasters.

Although solar energy systems may require a significant initial investment, continuous usage is cheaper than traditional sources in the long run.

Fortunately, with more technological advances in renewable energy sources, solar energy technology is bound to get more competitive.
