Renewable energy systems

The primary renewable energy systems are wind power, solar power, water power, biomass, and biofuels.

Renewable energy systems can be divided into two main categories with many subcategories of renewable energy technologies including wind turbines, solar PV panels, geothermal heating/cooling units just to name a few.

The main renewable energy source is the sun with three different types of renewable energies harnessed from the sun being photovoltaics for electricity generation, concentrating solar thermal for utility-scale heat or process steam production, and solar architecture which includes daylighting and passive design strategies using skylights or light tubes to provide lighting.

Solar technology has grown in capacity exponentially since its first installation in 1954 by Bell Labs to become the renewable energy source with the most installed capacity.

Solar technology can also be combined with other renewable technologies to achieve a net reduction in the consumption of fossil fuels.

The renewable energy system installed on Earth is solar-powered, atmospheric water generators collect potable water from humidity in the air and hydroelectric power plants are able to convert kinetic or potential energy into electricity through two types of technologies, either run-of-the-river which harnesses natural stream flows without any reservoir storage or by damming rivers to store water that then turns turbines as it passes through at a higher elevation.

About 97% of renewable electrical generation comes from renewable thermal and wind power while geothermal contributes about 3%, biomass gasifiers, kites,solar updraft towers, and renewable fuel sources such as but not limited to bioethanol, biobutanol, biodiesel, and biogas contribute very little renewable energy generation.

There are three main renewable heat technologies used today, biomass heating systems use waste wood for the primary fuel source while district heating is a centralized system that supplies district hot water or steam to multiple buildings through large piping networks either in urban or rural environments.

The third renewable heat technology is geothermal energy which makes use of the steady temperature below ground to heat homes or provides process heat rather than building surface heat exchangers.

Renewable energy systems have many benefits including environmental stewardship, economic benefits, and higher quality of life with renewable energy generation taking precedence over renewable heat generation.

Renewable energy systems do however have problems with renewable energy resources being intermittent and unpredictable, renewable energy resources are not constant counterparts of fossil fuels which generate a constant supply of electricity around the clock.

The variable nature of renewable resources is often compensated for by either grid interconnections or storage technologies such as batteries or compressed air tanks in order to balance supply and demand with renewable energy systems having a role in mitigating greenhouse gases.

Another problem with renewable energy systems is that they can be expensive when compared to traditional sources of renewable energy generation, renewable power generators account for about 3% of total worldwide power generation while the rest coming from fossil fuels with hydroelectric power making up most of the remaining amount.

Wind Power

In wind power, the renewable energy source is wind. Wind powers a set of rotors that spin a shaft which then spins a generator to produce electricity. It can be used indefinitely as long as there are high winds. No fuel is required to run the system and its environmental impact is very little aside from noise pollution from the devices themselves and the small amount of space they occupy. Wind turbines have been criticized for being inefficient due to their low energy output but they do not emit any greenhouse gasses during operation so they still help renewable sources gain a bigger share in energy supply compared to non-renewable, fossil fuel methods of production.

A new type called vertical axis turbine has been created by several inventors out there who claim it solves some of the issues turbines have. The design allows for a normal horizontal axis turbine but with the added feature of being able to operate in any direction instead of just going into the wind as usual. This means not only that it would be more efficient as it can produce energy from winds coming from different directions, but also that you could place it on your home and generate renewable energy from both sides without having to worry about changing its position all the time since you always have some wind blowing.

Solar Power

In solar power, an array is created using photovoltaic cells which are semiconductors that absorb light particles called photons and create an electric current when exposed to them (a battery works the same way). It’s important to mention that this process doesn’t happen during the night or when there is no light at all around it, like in cloudy days. Cells are mounted on panels that produce electricity (the power of the panels depends greatly on their surface area). They can be used to power your home but they may require many panels since each cell has a low production rate. This renewable energy source requires an initial investment to buy the materials necessary for any system and even if you manage to make one you will need trained persons (electricians) to set it up which makes this renewable method rather expensive.

Hydropower

The renewable energy source that comes from water is hydropower. This renewable technology operates by using dams built across rivers or other waterways to trap water flowing through them at high. When enough pressure builds up behind the barrier, turbines are activated which spin and generate electricity. This renewable energy source has the greatest potential for people living near rivers but it can also work in other areas where there are sizable bodies of water, like man-made lakes or even the sea.

This renewable technology is mostly used to power cities since renewable energy sources aren’t very common but benefits may still be achieved by using them on a domestic scale.

Biomass energy

A biomass facility would produce heat from burning plant matter which you could then use for heating your home. If that’s not possible then you could always cook or boil water with it as well. You will need a large amount of dry material to start this type of renewable energy system so if you don’t have any land suitable for growing crops nearby you will need to transport the biomass from far away.

The renewable energy source that doesn’t require any specific location is solar power. Simply put, renewable technology uses cells that capture light particles called photons to create electricity. Electricity generated this way can be used in many different ways, like powering your home or even charging batteries (to use renewable energy sources when there is no light). This renewable technology does not require much work to set up and you could make one yourself if you know how to handle semi-conductors and other electronic components but these don’t come cheap either.

To conclude we can say renewable energy systems are a great alternative to traditional fossil fuel-based energy production and they do their job quite well in most cases but it’s important to remember renewable technologies are often very expensive and you will require a lot of training to handle them making renewable energy systems a rare technology in the world today.
