After the launch of the solar boat, solar plane is here to play its part in the advancement of renewable energy. An experimental solar plane took its first test-flight this week. After the successful test flight, it has become possible for the Solar Impulse to plan of making a trip round the world.

According to reports, the test flight was expected to fly for about 90 minutes, reaching an altitude of about 1,000 meters.

The solar-powered airplane weighs about 1,600 kilograms and has four electric motors on board that supply the power to keep the plane up whether its day or night.

Energy production is one such process that is harming environment and due to which a major part of precious resources is fast depleting. Feeling the need of the hour, here we are going to explain some of the ways to our readers that would be of great help for them in preserving the energy, so that it can be utilized for better purposes.

Opting for natural energy resources

Though opting for the natural energy sources does not mean that you are taking part in conservation of energy, however, yet one must try switching on to the ways that require the use of natural resources for the production of energy. This would lower the burden upon burning and using the fossil fuels that are already depleting with a fast pace. Read the full story

United States already generate 45 billion kilowatt-hours of electricity from biomass and that is 1.2% of whole United States electric sales.

United States also produce 4 billion gallons of ethanol, which is almost 2 percent of the liquid fuel used in cars and trucks. Same like that contribution for heat is also considerable. But still it can be produced more by better conversion technology and more attention paid to energy crops.

There are many benefits of biomass energy but an appropriate use is required for reaping these benefits. The benefits of Biomass Energy are given below:

Small Carbon Footprint

As compared to fossil fuel the carbon footprint of biomass energy is small which is one of the major benefit of biomass energy. When new plant material is available to replace the used material, no net carbon dioxide increase is produces by biomass energy. Bio power reduces fossil fuel consumption which also reduces the release of carbon dioxide, this seems to be a good news but there is a problem that fossil fuels are often used for manipulation and harvesting of biomass.

Renewable energy is the energy, which is derived from naturally occurring non- depleting sources, such as solar, wind and hydroelectric power.

Energy sources like oil and coal are not considered as renewable energy sources, because they rely on burning a material, which must be extracted and cannot be recreated.

Renewable energy is often called environmental friendly, or green energy, as it makes use of clean natural resources, although certain types of renewable energy do produce pollution. With the increase in global demand for energy, renewable energy has become increasingly important as it is the only source of energy which promises to remain forever.

Researchers have designed a product that its inventors claim could easily produce between 15 and 20 times the total electricity the world uses today. Not only that, it could also be used as a desalination device and may be able to reverse the effects of global warming.

The researchers from the Technion – Israel Institute of Science seem confident that the “Energy Tower” could be a major solution to the world’s problems. They’ve been working on the concept since 1983, and together have spent more than 150 man-years researching, designing, testing, and analyzing.

As it is suggested by the term, bio-fuels are fuels that are formed by the decomposition of biological matter.

Mostly the bio-fuels are derived from plants and they exist in all the three states of matter:solid, liquid, and gas.

Differences Between Bio-Fuels and Fossil Fuels

The differences between bio-fuels and fossil fuels are:

• Million years are required for fossil fuels to build whereas bio-fuels can be made extremely fast. They take just few days to build.
• Huge amounts of pollution are generated by fossil fuels. As compared to bio-fuels fossil fuels are comparatively safer.
• Unlike fossil fuels bio-fuels are renewable sources of energy.

Different Types of Bio-fuels

There are four types of bio-fuels:

1. First generation bio-fuels,
2. Second generation bio-fuels,
3. Third generation bio-fuels, and
4. Fourth generation bio-fuels.
