Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

RESEARCHERS HAVE DEVELOPED A NEW, INEXPENSIVE CATALYST FOR HYDROGEN FUEL CELLS

Researchers from the University of Delaware have found a new way to produce inexpensive hydrogen fuel. The discovery could lead to less expensive fuel cells, as well, which may make these energy systems more attractive to consumers and businesses alike. Fuel cells are notoriously expensive because they are made using platinum. The high cost of fuel cells has made them somewhat unattractive when compared to other forms of renewable energy, such as solar power.

RESEARCH TEAM USES COPPER AND TITANIUM TO CREATE AN AFFORDABLE AND EFFICIENT FUEL CELL CATALYST

The research team from the University of Delaware, lead by chemical engineer Feng Jiao, have developed a new catalyst that uses copper alloy and titanium. The team found that combining copper and titanium produces better catalytic results than what can be found in traditional platinum catalysts. One of the major benefits of the new catalyst is that it is quite inexpensive. Using the new catalyst could make fuel cells more affordable and increase their performance capabilities. It could also lead to a new, inexpensive way to produce hydrogen fuel.

Commercialization Of New Catalyst Could Take Several Years To Achieve

Though the new catalyst shows a great deal of promise, it may be several years before the catalyst can see any commercial use. The research team has been experimenting with a small-scale catalyst, which serves as the first step for further research into making hydrogen fuel and fuel cells a more financially viable alternative to conventional forms of energy. Scaling up the catalyst will take time, and researchers will have to examine its capabilities before the catalyst can be commercialized in any significant way.

Hydrogen Fuel Cells Could Become More Popular Across Several Sectors

Hydrogen fuel cells are seeing the majority of their use in the transportation sector. These energy systems have become quite attractive to automakers because they produce electrical power without also producing emissions. Fuel cells have also been used in various industrial projects. Making these energy systems more affordable will likely increase their usage across various business sectors that have an interest in clean energy.

Tips For Choosing The Right Solar Panels For Your Home

Tips For Choosing The Right Solar Panels For Your Home
When it comes to choosing solar panels for your new solar panel system, the process can get a bit confusing. Consulting with a solar panels specialist like the experts at Solar Panels Perth can make the decision making process less complicated.

The cost of solar panels has dropped considerably in the last few years as more and more people see the benefit of using solar energy in their homes. Below you will find some tips on how to choose the best solar panels to fit your energy needs.

NEVER CHOOSE ON PRICE ALONE

Though it is tempting to choose the cheapest panels you can find, it is not always the wisest option. You need to be sure that the panels are going to fit in the area you have set up for them and that they qualify for the government mandated rebate that you can get when you switch to solar energy. Remember the old adage; you get what you pay for when you are looking for the right panels to use in your system.

CONSIDER TOLERANCE

You need to find out the panels tolerance. This is the range that the panel will either exceed or fail to meet when it comes to wattage. You need to see what both the positive and the negative wattage tolerances are for any solar panel you are considering.

DURABILITY

The durability of solar panels is important for quite a few reasons. The biggest reason is that you don't want to be stuck without electricity because your panels failed to withstand storms and other natural elements. You want a solar panel with no less than a 25-year warranty and you want to buy it from a reputable dealer.

FIND A REPUTABLE DEALER

You never go through the phone book and choose the first panel dealer you run across. Take your time and find a dealer that is reputable and well respected in the community. You will also want the installer to have a landline phone and a physical address, just in case something goes wrong while the panels are still under warranty.

CONSIDER THE MATERIALS

You will also want to do your research when it comes to the materials used to make the solar panels that you are considering for your system. There are three main types of solar cells and you want the best for your system. Do your research and determine which is the best fit for you.

These are just a few tips to help you find the best solar panels to suit your energy needs. Do your research; find the right installer for you and you will be happy with your system for many years to come.
