The whole automobile industry searched for a solution to overcome the economic and environmental crisis. More and more players in the market of automobiles are seeking the eco-friendly cars. Eco friendly cars use electricity; green fuel like ethanol, e-85 and biodiesel; solar power; hybrid motors and even natural gas to power itself. The eco-friendly automobiles may be hybrid electric vehicle (HEV), electric vehicle, or other eco-friendly ones.

Fiat Automobiles may be a great player in the market of eco automobiles. :-) Fiat Automobiles is regarded as the leader in Europe for developing eco automobiles. Fiat emerges as one favorite choice among used car buyers who wish to keep an eye on their budget and yet want the equally eco-friendly car.
 

Maybe you don't know Tesla. But the Tesla Roadster is the world’s first all electric sports car, but a little expensive, owned by a few rich guys now.

The environment of our earth is under high pressure. We face more and more serious problems about environment, such as the earthquake, the global warming, the abnormity of the weather. We have to do something to protect our environment. Below is about the eco-friendly vehicle. In fact at the top of many environmentalists' wish list is an eco-friendly vehicle. With this in mind, and in order to protect our environment, automobile manufacturers in the world have raced to the drawing boards anxious to roll out their version of the green machines.

This year in Detroit Auto Show, automobile manufacturers brought some eco-friendly vehicles. In fact in Detroit Auto Show 2010, Electric Avenue is opened, just for electric vehicles.
 

Below we briefly introduce some eco-friendly electric vehicles.

We may know Toyota Prius. It's so popular in the world. As the current leader in hybrid technology, Toyota has released a beautiful FT-CH concept, which is a full hybrid and is being tauted as a cheaper, younger, and smaller version of the Prius.

Because of this effect in Energy efficient, ECO and Reduce energy dependence, many countries and areas are involved this electric vehicles. Electric vehicles are propelled by an electric motor (or motors) powered by rechargeable battery packs. For example, Technical Specification for the Recharging System of Electric Vehicles have been formally implemented in shenzhen, China in 2010. This is the first recharging technology standard for electric vehicles promulgated in China, principally specifying relevant technology of recharging station of electric vehicles.

And even earlier in 2009, BYD, the giant in batteries in China, began selling a plug-in electric hybrid car in China, which is at least a year ahead of similar efforts in the U.S. and Japan.

Worldwide, hydropower plants (hydroelectric plants, Hydro plants), as one renewable energy (green energy, alternative power) source, produce about 24% of the world's electricity, supply more than one billion people with energy. The world's hydropower plants (hydroelectric plants, Hydro plants) output a combined total of 675,000 MW, the energy equivalent of 3.6 billion barrels of oil, according to the National Renewable Energy Laboratory. In fact there are more than 2,000 hydro power plants, which are operating, in the United States, making hydropower the country's largest renewable power source.

How do hydropower plants work? Hydropower plants (hydroelectric plants, Hydro plants) uses the force of moving water to make electricity. A typical hydro power plant is a system with three parts:

1. an electric plant where the electricity is produced.
2. a dam that can be opened or closed to control the water flow.
3. a reservoir (artificial lake) where water can be stored.

But do you know wind-powered hand-held charger? :-) It's not so popular. And I think someone know this cool gadget firstly. HYmini offers such cool gadget. It's palm-sized, comes in three colors (comes in black, white, and green), and can charge your gadgets with just a stiff breeze. It sounds cool, don't you think so?

All this wind-powered charger takes is a breeze of between 9 and 30 mph to keep the battery charging. Meanwhile, the translucent wind turbine glows green while in use, and the cool gadget contains an LED night light.

Solar water heaters, also called solar domestic hot water systems, is a cost-effective way to generate hot water for your home. Solar water heaters (solar domestic hot water systems) can be used in any climate, but different types of solar water heaters work best in different areas, and they use free sunshine. This will cut your bill for electricity.

Solar water heater includes two main parts: storage tanks and solar collectors. There are active solar water heating systems and passive solar water heating systems. The active ones have circulating pumps and controls, but the passive solar water heating systems don't. In fact there are many suppliers of solar water heaters in China. They perform differently mainly because of this.

Solar energy: Solar panels can be used to convert the sunlight into electrical energy. Some achievements of solar energy have been achieved during these years.
 

Wind energy: Wind turbines are connected to the generators, turn to generate electrical energy.

Hydropower: In the hydro-electric plant, water is stored in a reservoir. The water's potential power is converted to kinetic energy as it is piped into turbines that are connected to the generators.

Geothermal power: Geothermal energy harnesses the heat of our Earth to provide heating & electricity.

Biomass: Biomass is organic matter that can be converted to provide heat or electricity.

The sales of solar power panel were 5.6GW in 2008, which is up 48 percent. In 2008 3.3GW or 60% solar panel sales was produced in Asia. And about 1.5GW solar energy panel sales was produced in Europe. Only 750MW solar power panel sales was produced in the United States.

 

The downturn of alternative energy (green energy, renewable power) happened in 2009, and the manufacturing capacity utilisation was below 50%, which is similar to the semiconductor-for-IT industry. But in 2010 the solar panel market is picking up again

There's one revolutionary advancement for the development of solar energy. Caltech (California Institute of Technology) researchers claim they have developed a solar cell that is twice as efficient as conventional solar wafers and that could be much cheaper to make.

Using silicon-wire arrays, Caltech researchers claim they can trap up to 96 percent of incident sunlight at a single wavelength and up to 85 per cent of the collectible sunlight, then convert between 90 and 100 percent of it into electrons, aka electricity, surpassing previous optical microstructures developed to trap light. As we know conventional photovoltaic (PV) cells convert about 40% of the sunlight they absorb into electricity.

Solar energy is a kind of cheap energy source for Africa, clean, green, free, without pollution or damage to the environment.

Electrifying the rural areas poses great challenges for African governments. Remote and scattered, rural homes, which are unlike homes in the urban areas, are costly and often impractical to connect to the main electricity grid. But stand-alone sources of power, such as solar energy, wind energy and power from mini-hydro generators, can help to fill the gap of remote and scattered, rural homes. In Africa solar power, which is clean and renewable, fits the demands.

The sun is free and inexhaustible.
