What are the Advantages and Disadvantages of Using Green Energy Sources?
Today, we are now aware of the effects of global warming. Fortunately, it’s not too late and we can still change which is why many are pushing for green energy sources.

The advantage of using green energy sources is that it is clean so it does not emit anything harmful into the air which has an impact on the environment. It is also renewable which means we will never run out of it unlike oil which is expected to dry up in a decade or so.
Although green energy facilities are expensive to build, it requires less maintenance so you don’t have to shell out a lot of money to operate it.
It can also bring economic benefits to certain areas even boost tourism.

While these sound good, there are some who say that there are advantages to using such technology.
While green energy sources can produce electricity, how much it can generate is not consistent. This is because we have no control of the weather so if a certain area relies on solar energy and there is a weather disturbance, it will not be able to convert sunlight into electricity.
Building these facilities also requires a lot of land so we may have to cut on farmland which is what many are concerned about if more wind turbines are to be put up.
Another disadvantage is the fact that some of the green energy sources cannot be installed in certain areas of the planet. For instance, wave energy can only be utilized if the waves coming from the ocean reach at least 16 feet. The use geothermal energy can only be done in geologically unstable parts of the planet.
But if you look at such arguments, places that cannot use one form of green energy source can be substituted for another. If wind turbines need more space, they can be installed near the coast instead of putting these on land. A study shows that you can generate more electricity while these are in the ocean.
While the weather is something we cannot control, it is not everyday that there is a weather disturbance so this too shall pass. If solar energy is being used and the sun is covered, the emergency generators will be activated and use up the energy that was stored.
A very good example of this is called ocean thermal energy. Power is generated by harnessing the different temperatures in the water. It is currently being used on a small scale both in Japan and Hawaii.
In the US, only 7% of green energy sources are used nationally. This was much higher 11 years ago and if we don’t have to worry about the cost of oil or even reduce our dependency on it, we have to invest more in this clean energy.
We can get it from green energy sources such as biomass, biodiesel, geothermal, solar, water and the wind. These are things we have all around us and all it takes is for someone to harness it instead of relying on traditional non-renewable means to produce energy.

Seven Tips On Saving Energy in Your Home
Summary:
Most of the electricity used in a home is produced by burning coal, oil and natural gas, which release carbon dioxide - the world's largest contributor to global climate change - into the atmosphere. As a result, it is the energy choices people make at home that may have the greatest effect on the environment.
Few people realize that the energy used in a home causes more greenhouse emissions than a car.

The typical household spends $1,400 a year on energy bills, according to the U.S. Environmental Protection Agency and the Department of Energy. By following simple energy saving tips and purchasing products that are Energy Star-qualified, a typical household can save up to 30 percent or more than $400 per year on utility expenses and accompanying pollution.
Following are seven simple tips that will help keep the environment on the up, and energy bills on the down:
* Dirty air filters in a home's heating and cooling system can lead to higher costs and early equipment failure. Clean or change these filters monthly.
* Energy Star-qualified windows and doors can help reduce home energy bills up to 15 percent. Many manufacturers, such as Jeld-Wen Windows and Doors, offer a variety of attractive Energy Star-qualified products for significant energy cost savings.
* Air leaks can overwork a home's heating and cooling
system. Seal air leaks in walls, ceilings, and around windows and doors, and add insulation to the attic or basement to improve the comfort and durability of your home.
* Replace the most frequently used light bulbs with compact fluorescent light bulbs. Look for the Energy Star logo. These use 75 percent less energy and last 10 times longer than normal bulbs. Changing just five can save more than $60 a year in energy costs.
* Make sure to turn off all lights and electronics when you leave a room, and don't keep the refrigerator door open any longer than needed.
* When buying heating and cooling devices, shop during the off-season to take advantage of many manufacturers' seasonal sales promotions and rebates.
* Planting a tree for shade can reduce cooling costs by up to 25 percent. For best results, plant leafy shade trees to the south and west and evergreens to the north. Trees also help to reduce the greenhouse effect, not to mention beautify a front or back yard.
The less energy people use, the less energy power plants need to generate, which reduces greenhouse gas emissions and improves the quality of our air. Energy efficiency helps the economy, too, by saving homeowners up to 30 percent in energy costs each year.
