Types of Renewable Energy

You need to consider and compare the types of renewable energy available if you're looking to find ways to save money on energy while also helping the environment. The cost of fossil fuels is steadily rising while the cost of installing renewable energy systems is steadily falling. Here, we'll examine why renewable green energy simply makes sense.



Renewables, the Far Safer Energy Option

The demise of fossil fuels was totally predictable. After all, they are a NON renewable energy source, and we're simply running out of them. As these non renewable sources become depleted, the greater their cost. They also pollute the Earth's environment, so on that basis alone, there's no longer any excuse to rely on them. We cannot afford the eventual cleanup expenses.

So, what can we do?

Green types of renewable energy offer a far safer option for our energy needs. Alternative clean energy from green sources IS renewable and sustainable — sources like water (hydro), wind, and the sun will never run out.

If we tap into them properly and responsibly, we can be assured to have an infinite supply of clean, affordable energy that won't harm our environment or our pocketbook. You could say it's how God intended it to be.

Types of RENEWABLE ENERGY include the following:

Solar

Affordable solar power has become increasingly popular as a renewable power source, and it's what often comes to mind when people think of green energy. Radiation from sunlight is collected to produce usable electrical energy. It can be as simple as having a few roof solar panels or as complicated as a solar energy plant that generates enough electricity to power an entire community.

Solar PV panels are used to collect energy from the sun and convert it into electric current for immediate use or to store in batteries for use later. Solar power is one of the greenest and cleanest renewable energy sources available.

Wind

Renewable wind energy has been successfully used for centuries to pump water, power saw mills, and grind grain, but today's efficient wind powered electric turbines are nothing like the old Dutch windmills.

Commercial wind farms are already in operation and in the planning stages across the land. Smaller wind turbines are available for residential power generation, and if you live in a windy area far from neighbors, they can offer a clean renewable energy option with no byproducts or pollutants.

Hydro Electric

Water offers several types of renewable energy solutions. Hydro electric dams are what most of us are familiar with. Huge hydroelectric turbines produce electricity by the force of water directed through the dam.

In Canada, Quebec Hydro's gigantic James Bay Project is one of the largest hydroelectric systems in the world, producing 16,000 megawatts. It covers an area the size of New York State and generates eight times the power output of Hoover Dam.

In similar applications, waterfalls, river currents, and tidal bores can be harnessed, and it's hoped that harnessing the power of ocean waves can yield useful energy as well.

Geothermal

Geothermal energy is harvestable energy that's generated by the Earth's molten core. Sometimes, depending on the location, we can harness geothermal energy from geysers and hot springs for heating or producing electricity.

Most common, though, are heat pumps that extract warmth from the top 10 feet of the Earth's crust to heat houses and commercial buildings. Geothermal is thought to be sustainable and renewable, because the Earth is constantly heating.

Biomass

The term "biomass" refers to any biological material either living or recently dead. Fossil fuels could technically be considered biomass, but their original material has been dead so long that it's structure has been altered.

Burning wood is considered a good example of a biomass fuel and since trees can be replanted, it is considered a source of Green energy. Carbon dioxide is released in the wood burning process, but live trees absorb carbon dioxide making wood carbon neutral. So, by responsibly replanting as much wood as you burn, the net pollution effect would be negligible.

Waste animal matter, compost materials, and even some garbage can be considered biomass, creating new possibilities for generating sustainable energy.

The Future of Renewable Energy

Green power is definitely the way forward. There's no longer any discussion to the contrary. It's simply obvious to all that we cannot continue using non renewable, non sustainable energy sources as if there were no tomorrow.

We need a different energy solution and that solution is found in green energy. Research and development need to increase so we can develope highly efficient types of renewable energy to serve the power needs of countless generations to come.
