Most things in life require energy in order to function. This energy can come from various different sources, some of which are renewable and some of which are not. In recent years there has been much talk about renewable energy and the positive impact that is has. So why should you care about renewable energy?

Using a source of energy that is renewable is very cost-effective. As soon as a business or an individual has set up a means to generate their own energy they can wave goodbye to the utility bills. Solar power for example can be really useful to power the appliances within a home and to generate heating systems.

The natural resources of the world will not be consumed as quickly if people are using renewable energy. Over time gas, coal and oil are all being run down and this will lead to them becoming non-existent. Supplies of these naturally occurring substances are not infinite and eventually they will completely run out. Using energy sources which are renewable puts a stop to this happening.

Using renewable energy helps to keep the air around is fresh and clean. In comparison using non-renewable forms of energy will generate smoke chemicals which will pollute the air. Thankfully there is no pollution which is created from using a source of energy which is renewable.

Harmful and dangerous substances are not created through the generation of renewable energy. After all using wind, water or solar power to generate electricity does not involve any type of activity which creates by products. Unfortunately the same cannot be said for nuclear energy which is something of a tricky subject some people.

Unlike non-renewable sources of energy renewable energy will not be consumed eventually. For instance, those who use solar power will always be able to use the power of the sun. Wind turbines will always be able to harness the power of the wind to generate electricity. And the tide will always create enough waves to create energy which can be easily used.

Another reason to care about renewable energy is that it helps to slow down global warming. By using up fuel which creates carbon emissions and climate of the planet is changing, and not for the better. This results in plants and animals dying out in certain areas and people are starting to feel the effects too.

Most people would rather think about renewable energy rather than nuclear power. This is due to the potentially harmful situations that nuclear generators can create. Chernobyl being a case in point. Instead of living in fear of what nuclear power can do the majority of people would rather rely on renewable sources of energy.

The points above are just a few reasons why everyone should care about renewable energy. Not only is it much safer than many of the other forms of generating energy, it is also better for the planet. Anyone who cares about fossil fuels and protecting themselves and others should realize that renewable energy is the way to go.

Renewable Energy is energy derived from resources that are regenerative or for all practical purposes cannot be depleted. Sources such the sun and the wind, can never be exhausted and therefore called renewable. They cause fewer emissions and are available locally. Their use can, to a large extent, reduce chemical, radioactive and thermal pollution. They are a viable source of clean and limitless energy. These are the non-conventional sources of energy. Most of the renewable sources of energy are fairly non-polluting and considered clean except for biomass, a renewable source, is a major polluter indoors.

Sources of renewable energy or non-conventional energy are the sun, wind, agricultural residue, firewood and animal dung. Energy generated from the sun is known as solar energy. Energy derived from water is called hydroelectricity. Biomass is firewood, animal dung, biodegradable waste from cities and crop residue. It becomes a source of energy when it is burnt. Geothermal energy is energy derived from hot, dry rocks, magma, hot water springs and natural geysers. Ocean thermal is energy derived from waves and tidal waves.

Solar Electricity

When it comes to renewable energy, the most powerful and useful is the sun. The sun is available from sunrise to sunset and produces an unimaginable amount of energy each and everyday. What solar collectors do is to harness the energy from the sun in the form of radiation to be usable forms of energy such as heat and electricity, Solar cells in particular converts the sun’s energy into electricity. With technology being so advanced, solar cells are taken to a new level. There are recreational vehicles, cell phones and cars.

Solar Heat

Solar heating systems rely on a source of bright light, a surface or liquid that can absorb light and a storage device for the resulting heat generated. A greenhouse is a good example of this effect. Solar heat is by far the cheapest and most practical form of renewable energy in the world. Some practical uses are water heaters, ovens, cookers and home heating.

Wind Energy

From times long, long ago, sailing ships depended on the energy of the wind to get across oceans. Likewise wind energy was also used to work windmills for pumping water. Today, wind power is being used as a clean source of electricity around the world. Wind farms, as they are often called can provide enough electricity for thousands of homes at a time. The power of wind is used to turn turbines, which in turn is connected to an electrical generator and the gearbox inside the generator converts the energy of the spinning turbine into electricity.

Water Power

Hundreds of years ago, waterwheels were used to provide power for grain mills and lumber cutting. Hydroelectricity, as it is called today, produces over 60% of the electricity in Canada and 60% in the United States.

Global warming is a threat that will affect generations to come. The atmosphere surrounding us that supports life is a God-given gift. It must be protected. We should be leaders in efforts to curb global warming, not resistant followers.

Erin Hunt is an avid writer and activist. She discovered that many are still unaware of the dangers of global warming and thus created a website to educate others on how they can play a role in the fight against global warming. Find out how you can make a difference at

Smart Energy Systems: 100% Renewable Energy at a National Level (Full Version)
Denmark has decided to become independent from fossil fuels. For the sake of the climate, the economy, and in order to ensure security of energy supply. This film shows how this will happen based on research conducted at Aalborg University (

At present wind and solar energy already delivers a good share of Denmark’s energy, but renewable energy is a major challenge for an energy system that is built upon fossil fuels. Energy production from wind and solar fluctuates – it fluctuates as the wind blows. So what renewables are reliable when there is no sun or wind energy available?

Another challenge is the transport sector. How do we create an energy system of renewable energy, where also cars, ships and planes can operate on fossil-free energy? A great example of an energy system that will ensure Denmark a 100% renewable energy system is called: Smart Energy Systems – a coherent, fossil-free energy system that will create lots of new jobs and green energy for the Danes, both in terms of electricity, heat and transport.
