I need a few examples of alternative energy and what it is.

Alternative energy is a term that refers to methods of generating energy that are not the usual method (i.e. fossil fuels). There are many forms of alternative energy, but, as energy is conserved, you have to ask yourself where the energy comes from (and the answer is always "the sun"). You should always be careful when you look at energy forms, because some of them just won’t work – like the idea of putting water in your gas tank that another user has suggested (thermodynamics shows that these ideas won’t work).

The sun undergoes nuclear reactions which result in the release of photons (beams of light that have energy associated with them). Alternative energy forms just capture the energy from the sun in different ways (actually, fossil fuels also got their energy from the sun a long time ago).

Here are a few alternative energy sources and how they relate to the sun:

Bio-fuels: We can grow plants (such as algae, corn, sugar cane) which collect the photons from the sun and use the energy in the photons to create sugars. We can harvest those sugars and and turn them into liquid fuels such as ethanol.

Solar Energy: This technology directly harnesses the energy of the sun by absorbing photons through photovoltaic solar cells and which create an electrical current when they absorb a photon. Additionally, you can use the energy of the sun to thermally heat an object, which is referred to as solar-thermal energy.

Wind Energy: When the photons from the sun hit the air in the atmosphere, that energy can cause the generation of wind. We can harvest the wind energy by using turbines which spin when the wind hits them. The spinning motion is used to turn a generator which produces electricity.

Hydro-electric: When the sun hits water, it can cause the water to turn into a gas and later that gas can result in rain. If the rain occurs at a high enough elevation and gets held behind a dam, the water now possesses a high potential energy due to the energy from the sun. That energy can be turned into electrical energy by converting the potential energy of the water into kinetic energy which is then used to turn a turbine in a hydroelectric dam.

I came accross a new, proven and tested home made wind power system and solar power system which eliminates our electricity bills. It was written by a renewable energy enthusiasts Michael Harvey the diy called Earth4energy. You can get your copy to save energy and help environment while eliminating your power bills.

or possibly start my own green energy company?

I agree with the first poster about GE. I it is safe to say they are slowly becoming a diversified play in this industry. They are down due to the activities of GE capital, but that will change.

I strongly disagree with the second poster’s view of the economics of green energy. This is changing quickly. It may be the case today. However, some of the ROI on such things as solar thermal (not voltaic) are starting to beat out gas plants. Sure, solar and wind are surviving on tax subsidies that are causing false demand. However, that will change as hydrocarbons continue to have supply issues.

I recommend First Solar (FSLR). They are a profitable company, thought the valuation is high. But they are solid. I also like Sunpower (SPWR). These are less risky. There are tons of ultra small caps, but that gets risky. I advise staying away from ethanol as an investment. The unfortunate thing is that most of the good wind companies beyond GE are in Europe and trade on other exchanges.

I cover FSLR on my blog:

With so many countries cutting back on energy use, there are many governments looking for alternative sources of fuel, especially with the rapidly climbing gas prices. The US is working harder than ever to get other sources of power onto the market. Experts say that not only are gas (octane) fuels pollutant, but the supplies buried beneath the earth are dwindling quickly. Now, with the anxiousness of a fuel crunch looming over our heads, America is finally stepping up and trying to find some other way to fuel our mechanical marvels. Here are the top candidates for alternative fuel king.

Bio diesel is the result of the European effort to remove a considerable amount of the polluting attributes of diesel fuel. This has created a 60% reduction in hydrocarbons, a 40% reduction of carbon monoxide, and a 40% reduction in particulates. Bio carbon is produced from raw materials called feedstock. This material absorbs carbon monoxide in an amount equal to the amount the car using the fuel emits. With this new diesel fuel, diesel engines are working at 50% higher fuel efficiency than normal gas powered engines

Ethanol is, by far, the most popular of the alternative fuels. Ethanol has a very down home farm essence to it as it is made from starch producing plants like corn. Yes, corn is the fuel of the future, although some producers prefer sugar to corn in the ethanol making process. Today, most of the information you hear about ethanol is the E85 mixture, which is a mixture of 85% ethanol, and 15% gas. This alternative fuel can only be used in vehicles especially designed for them as well as vehicles that are 22 E85 compatible. Using ethanol can reduce smog production up to 50%, gas can’t say that much. Unfortunately, despite E85’s smog emission reduction it is still contributing to ozone depletion, although many experts disagree, and still others have no idea how it happens in the first place.

CNG, or Compressed Natural Gas, is another of the top candidates for the king of alternative fuels. In comparison to gas, CNG comes from domestic, not Middle Eastern Reserves, burns cleaner, and is cheaper. Unfortunately, vehicles that run on CNG require some changes which include: storing natural gas in pressurized tanks, burning the CNG with a modified combustion engine, and it is more economical than gas burning engines. Although, CNG cars emit fewer smog emissions than Hybrid cars, they release more greenhouse gases than Hybrid cars as well.

Besides these top 3 candidates for alternative fuel king, there are other less developed methods. There is liquid coal, which will be too costly to use. There is hydrogen fuel, which will also be costly, because hydrogen isn’t naturally found. Fuel cell technology, which sounds a lot like Star Trek, is light years away from being developed. As of now, the hybrid vehicle is probably your best bet as far as fuel efficiency, and fuel alternative. Unfortunately, it doesn’t cure us of our dependency on gas. The king of alternative fuel may soon be crowned, but that soon is far away.

Do you drive as often, as you drove prior to the oil increase, for vacations, work, recreation, etc…?

Is the utility company in your community helping, ignoring or hurting (increasing bills) the current home energy costs?

With the cost of per barrel of oil rising to $100 per barrel of oil and is expected to go past the $100 per barrel mark, do you have any thoughts/suggestions as how to cope with the high cost of energy needs.

people can get together and demand cheap solar electric cars, hybrid cars, (that car that makes water is a GM disaster)… we are making allot more ethanol . oil will always be needed for plastics.

plus we got plans for building alot more Nuclear plants.

With the alarming environmental concerns and the aim of preserving a greener tomorrow, automakers are triggered to build more environment-friendly automobiles. In fact, part of the fast-rising vehicles today is powered by alternative fuels. In a short span of time, these vehicles have swiftly stolen the limelight of the industry.

Alternative fuel, also known as non-conventional fuels, is any material or substance that can be used as a fuel, other than fossil fuels, or conventional fuels of petroleum, coal, propane, and natural gas. The term usually refers to a source of which energy is renewable. Its main function is to store energy in a form that is stable and can be easily transported from the place of production to the end user. Alternative fuels include biodiesel, butanol, ethanol, chemically stored electricity like batteries and fuel cells, hydrogen, methane, natural gas, biomass, wood, wood gas, vegetable oil, and peanut oil.

One of the vehicles using such alternative fuels is the Volvo Multi-Fuel. Said vehicle is optimized to run on five different fuels so there is a need to upgrade on Volvo performance parts. The Volvo Multi-Fuel, based on the Volvo V70, is powered by a 2.0-liter five-cylinder turbocharged engine that will run on hythane (10 per cent hydrogen and 90 per cent methane), biomethane, natural gas (CNG), bioethanol E85 (85 per cent bioethanol and 15 per cent gasoline) and gasoline.

Aside from the fact that it runs on 5 different engines, another notable facet of the Volvo Multi-Fuel is its relatively consistent performance not considering the fuel used. Volvo claims that the turbocharged engine of the vehicle is producing about 200 horsepower. It is sufficient to power up the wagon. The vehicle runs exceptionally clean. In fact, when pure renewable fuels such as hyrdrogen, biomethane or bioethanol are used, very little fossil carbon dioxide is emitted.

Hythane, E85 bioethanol and CNG biomethane are extra-clean fuels. This is main reason why the vehicle has surpassed all existing emissions regulations imposed in any market at the present time. Furthermore, it would also qualify for the upcoming EuroV emissions regulations. The mentioned fuels also have the advantage of being carbon neutral. It means that the amount of carbon emitted when the fuel is burned is equivalent to the amount acquired by the crops used to make the fuel.

When changing between fuels, the driver only has to choose between gaseous or liquid fuel and the engine management system will adjust to optimize performance for the fuel. The Multi-Fuel has separate fuel tanks for gaseous fuels that include hythane, biomethane and CNG; and liquid fuel like E85 and gasoline.

“The whole car is optimized for high performance, driving on any of the five different fuels,” said Mats Moren, project leader engine at Volvo Car Corporation. “It is a step towards a hydrogen-powered society. Perhaps we can develop the system even further, to run on a higher blend in the future.”

Volvo is known for its commitment to lead automotive milestones. As a fact, it has been associated with remarkable safety and ninety-degree bodywork. At this point in time, the automaker has already established a name that embodies style, quality, cutting-edge design – and superb green technology.

Aside from Volvo, renowned automakers like Daimler Chrysler are producing entry vehicles that use alternative fuels. The latest entry so far is the E320 CDI BlUETEC that runs on a biomass-to-liquid (BtL) fuel known as SunDiesel. Said fuel can be used as the lone fuel or as an additive. “We believe BtL fuels can make an important contribution to our energy supply,” explained Prof. Dr. Herbert Kohler, vice president of the Research Body and Powertrain and also chief environmental officer of DaimlerChrysler AG. “They can reduce our dependence on fossil fuels, and with their good carbon dioxide audit they can also help make mobility more environmentally compatible.”

The Mercedes-Benz E200 NGT and the smart four two cng were also entered, both running on CNG. The E 200 NGT reduces CO2 emissions by over 20 per cent and with a power output of 163 horsepower from the 1.8-liter engine. It is the most powerful CNG passenger car currently in production. The driver can decide whether to use CNG or gasoline using buttons on the steering wheel, and an electronic control unit ensures a smooth transition from one power source to the other. Fuel consumption is 39 mpg with CNG and 26 mpg with premium unleaded.

Ford’s green vehicles include Focus C-MAX H2 ICE is powered by a prototype hydrogen internal combustion engine. The engine is a 2.3-liter four-cylinder gasoline engine that produces 110 horsepower. According to Ford the Focus C-MAX H2 ICE has a driving range of about 120 miles with the fuel capacity of 2.75 kg of hydrogen.

General Motors newest entry is Saab 9-5 BioPower, which runs on either bioethanol or gasoline. The BioPower is not only environment-friendly; it also but delivers more power and performance than the gasoline-only version. The vehicle can switch between bioethanol and gasoline without any adjustment by the driver.

The Q7 TDI, powered by 3.0-liter direct-injection with impressive fuel economy of 22 mpg, is Audi’s latest green SUV pride. For the recently held Challenge Bibendum, the Q7 TDI was fueled with Synfuel produced by Shell. It is manufactured from natural gas, biomass or coal to decrease the environmental impact by reducing exhaust emissions.
