Alternative Energy: Love the Environment, Save More

The buzzword for the last 10 years is "alternative energy." A lot of environmentalists, economists, and home owners are labeling it as the last-ditch effort to protect Mother Earth, as well as boost a country’s economy.

Seriously, what’s with renewable energy sources that make them very popular and controversial all at the same time?

The Numerous Advantages

There are indeed so many reasons to love alternative energy. Topping the list is the fact that it is highly economical, and, despite its expensive installation cost, practical.

The word “alternative” is just another term for “renewable.” This means that the source of your energy can be replenished for all eternity. For example, the energy from the sun will never run out unless it becomes a black hole. The wind will always be present as long as there will be cold and hot air. The inner cores the earth are constantly boiling, making them good sources for geothermal energy. The kinetic energy they produce can then be converted into electrical power.

At an economic standpoint, you will never run out of sources for your electricity. This is in contrast with fossil fuels and coals that are now constantly being depleted that they will soon become very rare commodities. This will then further increase their price in the market, and consumers have to pay more for their usage.

Moreover, since home owners and businesses no longer have to completely depend on conventional sources for electricity, they can now reduce their utility bills to as much as 90 percent every year.

Second, there are already a lot of countries that are adapting alternative forms of energy for sustainability, and they are inviting their citizens to patronize them by offering tax breaks and tax credits. That spells more savings for families and businesspersons. The government is also able to save since they don’t have to spend a lot of money on importation.

For the past few years, there is the emergence of green jobs. These are positions that have been created due to the need of expertise and skills in running and managing these forms of energy. In the process, clean energy is able to generate jobs for plenty of individuals. The wind industry alone already employs 2,000 people in the United States. These renewable types of energy also opened plenty of doors for those who want to go into business. They can manufacture parts in producing wind turbines, hybrid cars, or solar panels. They may also be tapped to sell renewable energy kits to residences and small businesses.

A lot of communities are now able to sustain themselves economically. For instance, they can develop their own wind farm and sell electrical power to households in the area.

These energy sources are also considered to be very environment friendly. This is because they don’t give off carbon emissions that would only further damage the earth’s atmosphere and promote global warming. They don’t pollute the rivers or seas, destroy the forests, or cause health hazards to people.

Types of Energy Sources

The good thing about alternative energy is that there are so many of them that you can choose from—and there will be more in the coming years as technologies and science continue to improve. You can opt for the most ideal one based on a number of factors or learn to combine them to generate full electricity for your property.

One of the most popular is the solar energy. As its name implies, the power actually comes from the sun. To collect the energy, they make use of photovoltaic cells with silicon, boron, and other materials. These cells are then grouped together into frames or solar panels. They are the ones that absorb a certain amount of power from the sun that allows electrons in the cells to move freely and create current.

The panels are sometimes attached to a battery, which is then used as an energy saving device. Whenever there is not enough sunlight, the stored power can be used to generate electricity.

Another alternative energy will be wind power, which can be converted into electricity by means of an alternative energy source called turbine. Wind is simply defined as air movement. The cold air goes down just as the hot air rises. Because wind has its own mass and motion, it develops kinetic energy, which can then turn the blades found in these turbines. The blades are then controlled by the rotor. You will also find an enclosure composed of gear box, which speeds up the rotation and help produce more wind energy, and the generator, which converts wind power to electricity.

Then you have the alternative energy called hydroelectric power. More than 1 billion people all over the world are taking advantage of water energy for electricity. The way they function is very similar to wind power. The only difference is that the source of the kinetic energy will be the strong flow of water.

Though hydroelectric power plants are stable since they have been around for several years, they can also be pretty unpredictable. This is because they are highly dependent on the bodies of water of the earth as well as the rain that falls to the ground. If the weather is going to be too hot, the amount of water in these plants will drop, making it harder for them to generate enough kinetic power that can be converted into electricity.

A unique form of alternative energy will be biomass. The energy is derived from plants, even while they are still alive, to materials that are derived from them such as dead wood, food crops, and alcohol fuels. Though both fossil fuels and biomass give off carbon dioxide, new plants are able to absorb the element from the dead living things; hence, they can help lessen global warming. There are many ways on how to utilize biomass energy.

Then you have geothermal energy. This alternative energy is derived from the inner core of the earth, which is usually hot, and the heat that comes from the sun and touches the land’s surface. There are many uses of geothermal power. One of these is the production of electricity. But its efficiency is quite low, just less than 25 percent, and there could be a significant wasted exhaust heat. Hence, most plants would also use geothermal energy for heating buildings and greenhouses
