We are all aware of the harmful effects of global warming, but there can be many ways to prevent global warming. Although we can’t prevent global warming completely, we can sure help to reduce the intensity of the future effects of global warming.

global warming Prevention

Here are some steps that we can take in our daily lives to prevent global warming effects.

  • Use transportation only for travelling to far off areas. Try walking for short journeys or using a bicycle more frequently.
  • Share transportation and do car-pooling whenever possible.
  • Drive in the correct gear to reduce fuel usage. Keep all windows shut on warm days if you have air conditioning to maximize fuel efficiency.
  • Consider purchasing a hybrid or electric vehicle when looking for a new car.

Having dished out plenty of solar power info, I got to think whether or not the majority of people are even unaware of the brains behind the project, the Solar Panel? Whatever the metaphor, lets familiarize us with the photovoltaic physical workings of this super hero enigma.solar.panel.grid[1]

How They Do And What They Do?

As mentioned, the principles of photovoltaic physics are used to convert the energy of the sun in to electricity rather than just heat. Now the impressive scientific stuff has been duly noted, let me paint a much simpler picture.

Solar cells are not made using pure silicon but instead have impurities added to it. Why? Because pure silicon crystals are non reactive in a stable state, which is not good as the electrons need some form of instability to be productive. So in this context some impurities must be required.

Benefits of Biomass Energy

by Yasir on February 7, 2010 · 0 comments

in Bio Fuels

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:

7

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.

Our Earth receives 174 petawatts (PW) of solar radiations at the upper atmosphere, out of which almost 30% is reflected back to space whereas the rest is absorbed by clouds, oceans and land masses.solar energy

The Earth’s land surface, oceans and atmosphere that absorb solar radiation, raises their temperature. This causes warm air that contains evaporated water from the oceans to rise, causing atmospheric circulation or convection.

The water cycle gets completed when the air reaches a high altitude, where low temperature prevails, and the water vapor condenses into clouds, which rain onto the Earth’s surface.

Hydropower, or water-power is power that is generated from the energy of moving water, which may be harnessed for many useful purposes.

water am

Before the availability of commercial electric power became widespread, hydro power was used for irrigation, and used to operate various machines, such as watermills, textile machines, sawmills, dock cranes, and domestic lifts.

Hydropower is one of the oldest methods used to harness energy, and has been used for hundreds of years. Water wheels and watermills were built in India; water powered mills produced flour from grain in Imperial Rome, and were also used for sawing timber and stone.

The power generated from a wave of water released from a tank was used to extract the metal ores in a method known as hushing. This was extensively used in Britain in the Medieval and later periods to extract lead and tin ores. The same method later evolved into hydraulic mining when used during the California gold rush.

Solar Power is gaining popularity, becoming a key source of energy, all over the world due to a number of benefits of using solar power. Solar power can be utilized using a PV system or simply through a solar pool cover, solar garden lights or as a solar oven.

benefits of solar

There are multiple benefits of a solar system, which may even persuade you to consider using solar power in the future.

1. Environment Friendly

Solar power is a clean source of energy that releases no pollution into the air, thus helping prevent global warming and all other sorts of pollution.

Want to get your solar system built? Great! But wait, have you considered everything you need to? Just to be sure, have a look at the next 10 points, 1 for each finger.

solar power

1. First things first, what do you want? A solar hot water system or a system to generate electricity? Or is it both?

2. Where do you sit geographically? Your solar panels need to be orientated to receive the most sunlight they can daily and according to the season. General rule of thumb is to have them facing due south if you’re in the northern hemisphere and north if in the southern hemisphere thought a 45 degree variance shouldn’t make a huge impact in terms of performance.

According to a collaboration led by the Researchers from the U.S. Department of Energy’s Joint BioEnergy Institute (JBEI), they have successfully developed a microbe that can produce an advanced biofuel directly from biomass.

microbes for Biofuel

Making use of synthetic biology, the JBEI researchers have engineered a strain of Escherichia coli (E. coli) bacteria to produce biodiesel fuel and other important chemicals that are derived from fatty acids.

The Chief Executive Officer for JBEI, Jay Keasling said that the fact that microbes can produce a diesel fuel directly from biomass with no additional chemical modifications is exciting and important and a leading scientific authority on synthetic biology.

in Bio Fuels

In the context of renewable energy, biomass means both recently deceased and living biological materials such as plant & animal matter, dead trees, yard & wood chippings, which help in the production of chemicals and heat as well as bio-fuel. Oh and lets not forget biodegradable wastes too that can be burnt as fuel too.

Biomass is grown for industrial use from several plant types, such as,

  1. Corn,
  2. Miscanthus,
  3. Willow,

RV Solar Panels

by noor on February 4, 2010 · 0 comments

in Solar Energy

You may not be aware of this, but if you own a RV, i.e. a recreational vehicle, then it may be possible to get a number of solar panel solutions that can help you out in time of need.

rv solar panels

One of the main benefits of installing RV solar panels is that they can produce electricity even in remote locations. So if you are stuck in some far off area, without any patrol or gas, then this might come in handy for you.

The cost of RV kits can range from around $400 to $1000, depending on the power output you require.

RV solar cells are available in a variety of packages, which include starter kits or RV solar array extensions for addition to a current RV solar electricity system. The most widespread way to attach RV panels is by fixing them to the roof. This can be done by using mounts which screw into your RV roof.

Although wind energy is a great source for renewable energy, there are many issues related to the impact of wind turbines on the surrounding environment, which contribute to the significant level of disadvantages of wind turbines.

wind farm

In this article, I will discuss some of the impacts of wind turbines on the environment, and the disadvantages of producing electricity through wind turbines.

Noise Pollution

The most significant impact of a wind turbine on the environment is noise pollution. Although many people think that wind turbines are a great source of energy, a large proportion of these people would definitely oppose the development of a wind farm close to their home.

This is mainly due to the excessive noise, which is equivalent to that of a small jet engine. This noise pollution also lowers the property values within a varying radius of the construction area.
