A Darrieus Wind Turbine

Almost all countries of the world are starting to realize that the time for the exploitation of the power of the wind is right now. We realize that due to the surging power demand and the burgeoning environmental problems associated with generating energy, we are now faced with the challenge of getting things done.

Yes, in some respect, the entire problem can sometimes be disappointing and to a certain degree depressing. However, we are still fortunate because there are now emerging solutions to the world’s power needs if they are simply applied and developed to their fullest and most efficient potentials. Solar energy is starting to make a big headway in technology and implementation comparable to other alternate energy solutions.

Aside from solar technology, one of the other alternatives is wind turbine energy. The wind is a great source of renewable clean energy that is actually making great strides in reducing the use of coal power energy.

What is a wind turbine? A wind turbine utilized in the generation of electricity is not all that hard to comprehend even for ordinary citizens like you and me. It is actually functioning and designed like the water wheels which people of centuries ago used in the making of the flour. The main variation is that here we are using wind rather than water. The wind is the one that pushes the blades of the wheel to turn which in turn creates electricity in conjunction with some gears, magnets and resistance. As of the present, the energy created from the turbine cannot yet be stored in batteries so it is very necessary to use back-up systems but. Generally, however, it is a quite proficient system.

In generating energy from the wind, it is all about three factors: location, location and  location. Because we can not store the generated energy in batteries for subsequent use, it is important to emphasize where the wind turbines are located. Since the electricity generated has to be sent along the power lines and used right away, the turbines need to be located in a place where the wind is regularly blowing. The turbine needs to be located where there is a constant wind most of the time, but it also needs to be located in a place where there are other turbines as well.

While one turbine can generate quite a bit of energy, it may not be adequate to make it economically feasible. You must have hundreds of turbines to make it works feasibly and profitably. There are many places around the world where this is possible but the overall notion is very much regional in nature. In other words, the power made in Vegas should be used for consumers in the Vegas area. The energy generated in West Texas must remain in that place. This is not actually a good idea so that larger cities can derive some of their power from the wind turbines decreasing the demand for coal power.

With a new focus on alternative power sources, we are positive that wind power is only at the start of its surging popularity.

Capturing Solar Energy

Currently, there are already a lot of viable types of renewable energy as replacement in whole or partial for the traditional fossil fuels. When we say renewable energy, it usually refers to energy from such sources as geothermal heat, sunlight, tides, plants, rain and wind – and all are naturally renewable in nature. As of now, less than 10% of the world’s energy capacity is sourced from natural energy.

Wind power is considered to be the cleanest and the most proficient kind of renewable energy. Consequently, this is steadily gaining worldwide popularity. In Europe, there is a tremendous surge of wind power usage as many countries are investing money in constructing off shore wind farms. And it is nothing to wonder about as only a light breeze is the main requirement to generate this very efficient power.

Aside from companies and organizations investing in large-scale renewable energy production, some technologies behind renewable energy can also be adopted to small-scale grid and even that of residential use type. Just take a look at solar power. As the sun is available for half of the day, it can easily complement other energy sources. Buoyed by government subsidies and promotion, the cost of solar cells is steadily dropping which prompts businesses and individuals to take advantage of the free sun power.

An old renewable energy is coming from raging water which is hydropower. This is already very popular as this has been used for many decades with the use of dams. You might be familiar with Hoover Dam, the world’s largest hydropower. With water speedily flowing from a high spot to a low spot, it generates energy which is transformed into electricity. Hydropower is also possible even without using dams as long as there is a constant current or tide.

Courtesy of the recent oil crisis, biofuels like bioalcohol or bioethanol came into focus. This fuel is produced from the process of fermentation using corn, soy or sugarcane. In its pure form, it can then be used as a substitute to gasoline. Biodiesel can also be made from animal fat, vegetable oils and even recycled grease. Though these fuels can still produce emissions, they are considered as much cleaner and quite beneficial to the machine using.

Renewable energy is here to stay as we know that the conventional fossil fuels will soon be depleted and quite detrimental to our environment.

Wind Power

Humanity’s overdependence on fossil fuels must come to an end. The race for greener and more sustainable alternative energy is on. With the help of modern technology, it is hoped that in the coming decades the energy market would be singing a different tune.

As one of the promising energy resources, wind power generation is now generating a lot of interest from different players and investors. Researches are continually developing more energy efficient and cost effective wind turbines. Taking advantage of the wind power, wind farms sprouted all over the country. In response to animal rights activists, new wind turbines are not endangering birds which is a problem with the older type of wind turbines.

The most popular alternative energy supply is actually the energy from the sun or solar energy. To harness the power of the sun, solar cells are being utilized to gather as well as focus the energy directly from the sun, and convert it into electricity or hot water. Just like wind power, solar energy is zero in the pollution scale.

Scientists are now also looking into ways on how to exploit ocean wave energy. It is recognized by the government and the energy sector that ocean wave holds huge power potential.  In France, an ocean wave generator is successfully doing business and other interested investors in Ireland and Scotland are also interested to further develop the technologies behind ocean wave energy. Hopefully, more and more investors will pour in their money for alternative energy generation.

A perennial favorite, hydroelectric power has been utilized for decades already and this is known as cleaner energy compared to a grid. But then, because hydropower will only be possible with the presence of huge amount of water, it is essentially limited both in scope and applicability. To remedy this situation, some groups are encouraging small hydroelectric generators which usually supplied power to specific and exclusive local communities.

Next in line is geothermal energy. Geothermal is considered as abundant because it lies below the surface of the earth. The energy is created through the heating of water by earth’s extremely searing molten core. The cycle goes this way: the water is converted into steam and steam can be exploited and utilized to drive turbine engines on and this finally generates electricity. With geothermal’s great potential, studies and research are now underway to optimally develop it for the greater good.

Looking for more, interest on the so-called waste gas energies is winding up. This is actually referring to methane gas – which is in a very unique position to turn around the customary energy-pollution bond through the creation of energy from waster materials. The technology behind harnessing methane gas is very much applicable in garbage dumps. Methane gas can be use for fuel cells and in standard gasoline generators.

A politically charged and highly debated energy source, ethanol is a gasoline replacement and is a by-product of wheat, sugarcane, grapes, strawberries, corn, and even wood chips and wood cellulose. With the looming food crisis and the government subsidy to this sector, it is not a wonder why ethanol is at the center of many political debates.

For green-minded fellows, biodiesel energy is for you. Biodiesel are manufactured from plants’ oil.  So far, identified sources of biodiesel are soybean, rapeseed, coconut and sunflower oils. Biodiesel is cleaner than the regular diesel fuel. With a big potential market here and abroad, investors are now finding their place in this sector to hopefully cash in when the right time comes.

Atomic energy or nuclear energy is now widely used by many industrialized nations. Using nuclear fission, the energy derived is cheaper and efficient compared to the traditional power generation. The only big concern though is the disposal of the radioactive waste product.

As a person concerned with the connection between a healthy ecology and a healthy individual, it is my prevent wish that eventually we will find more alternative and greener energy sources.
