To many people, the differences between “alternative energy,” “renewable energy,” and “clean energy,” might not be obvious. But each term is unique and has its own individual definition. These three terms are not all exactly the same.

Alternative Energy

When we speak of alternative energy, we refer to sources of usable energy that can replace conventional energy sources (usually, without undesirable side effects). The term “alternative energy” is typically used to refer to sources of energy other than nuclear energy or fossil fuels.

Throughout the course of history, “alternative energy” has referred to different things. There was a time when nuclear energy was considered an alternative to conventional energy, and was therefore called “alternative energy.” But times have changed.

These days, a form of “alternative energy” might also be renewable energy, or clean energy, or both. The terms are often interchangeable, but definitely not the same.

Renewable Energy

Renewable energy is any type of energy which comes from renewable natural resources, such as wind, rain, sunlight, geothermal heat, and tides. It is referred to as “renewable” because it doesn’t run out. You can always get more of it.

People have begun to turn to this type of energy due to the rising oil prices, and the prospect that we might one day deplete available sources of fossil fuels, as well as due to concerns about the adverse effects that our conventional energy sources have on the environment.

Of all the different types of renewable energy, wind power is one which is growing in its use. The number of users who have some form of wind power installed has increased, with the current worldwide capacity being about 100 GW.

Clean Energy

“Clean energy” is simply any form of energy which is created with clean, harmless, and non-polluting methods.

Most renewable energy sources are also clean energy sources. But not all.

One such example is geothermal power. It may be a renewable energy source, but some geothermal energy processes can be harmful to the environment. Therefore, this is not always a clean energy. However there are also other forms of geothermal energy which are harmless and clean.

Clean energy makes the less impact on the environment than our current conventional energy sources do. It creates an insignificant amount of carbon dioxide, and its use can reduce the speed of global warming – or global pollution.

As you can see, alternative energy, renewable energy, and clean energy are very similar. But it is important to know that there are differences.

There are many actions which can be taken, to help reduce the greenhouse gases in our atmosphere. Some of these steps can be taken in your own home. Many clean energy solutions can can be easily installed, and some kits are quite affordable.

Carbon emissions and other forms of pollution are not only created by heavy industrial factories. They are created in the common household as well. Energy efficiency has become an important aspect of our lives.

It’s important to start making changes now; if we want to save our planet for our children, for the flora and fauna of the Earth, and for the future of mankind. Clean energy, to be exact, can make a big difference.

Renewable energy has its uses but they aren’t all advantageous. In this piece some of the benefits and adverse effects of renewable energy are considered and examined in different forms of renewable energy.

When people think or energy sources, they mostly think of coal, natural gas and oil, these fuels have been the source of energy for a number of years. However one problem is that they are limited in supply and availability.

Estimates have shown that the currently available sources will only meet our current energy demands for about 50 to 70 years or so. In order to find alternative sources of energy the world has decided to pursue renewable energy sources. However even renewable energy sources have their advantages and disadvantages too.

The available renewable energy sources that we have include solar, hydro, wind, geothermal, ocean and biomass. The most common of these advantages is that they are clean energy sources and do not pollute the air. They also do not contribute to global warming or greenhouse effects. Because the sources of such energy are natural the cost of operations are substantially reduced and they require less maintenance on their plants. One common disadvantage is that it is impossible to produce large quantities of electricity than can be done with fossil fuels. Because they are new technologies the costs of initiating them is also high.

Solar energy utilizes the energy from the sun. It has its advantages because these systems can easily fit into existing buildings and do not affect land use. Since the area that these collectors rest in is quite large, a lot more materials are needed. Solar radiation is also controlled by geography too. It is also limited to the daytime as well as non-cloudy days.

Wind energy makes use of the power of the wind in order to create electricity. Though it produces the most jobs it is reliant on strong winds too. Wind turbines tend to be large and though the areas under them can be used for farming, most people think of them as unattractive looking. These turbines are also very noisy to operate and they threaten the population of wild birds too.

Hydroelectric energy makes use of water in order to produce power. It is the most reliable of all energy sources that are renewable. Its disadvantages are that it affects the ecology and causes downstream problems. Decay of vegetation on the riverbed can also cause a buildup of methane which contributes to the greenhouse effects. Dams may also cause an alteration of the natural river flow and affect wildlife in the area as well. Water which is colder and which is lacking in oxygen tends to be released into the water this kills the fish, sudden release of water like this may also result in flooding.

Geothermal energy makes use of the steam from the Earth’s ground in order to generate power. It uses a smaller land area that other types of power plants. They can literally run continuously throughout the year. The disadvantages tend to be that these plants are site specific and it can bring up toxic chemicals and heat from the earth when it tries to obtain the steam. Drilling such geothermal reservoirs can also cost a lot.

Biomass electricity is made from the energies of wood, agricultural and municipal waste. It tends to help save on landfill waste but the transportation is also expensive and tends to affect the diversity of the land. Other than this the process is quite complex and should be much simpler.

Ocean energy is a clean and abundant energy form. It tends to be expensive and in order to access this energy, you need at least a 40 degree Fahrenheit difference in water temperature throughout the year. Other than this, the construction and putting in place of pipes may damage the ecosystem.
