Geothermal energy is energy obtained by drumming heat from the earth itself. This comes from magma and the radioactive rot of uranium, thorium, and potassium.

The downside to geothermal energy is the incontrovertible fact that it is expensive to build. Alternatively, because the earth’s crust steadily rots replenishing the heat, it is still a renewable source of energy.

There are 3 sorts of geothermal plants around. These are specifically dry steam, flash, and binary.

Dry steam plants take steam out of breaks in the ground and use it to directly drive a turbine that spins a generator.

Flash plants take on water at temperatures over 200C, out of the ground, and permits it to boil as it rises to the surface then separates the steam phase in steam/water separators which runs the steam thru a turbine to generate electrical power.

Last, you have binary plants. Here, hot water flows through heat exchangers and that boiling organic liquid is what spins the turbine.

Once power is generated, the condensed steam and remaining geothermal liquid from all 3 kinds of plants are injected into the hot rock to pick up more heat.

Geothermal plants are used operational in different parts of the world. These are often located in geologically unsound parts of the planet. You can see some in Chile, Iceland, New Zealand, US, the Philippines and Italy. At home, 2 most prominent areas for this are in the Yellowstone basin and in northerly California.

Aside from digging deep into the earth, there are some who believe we will generate power from hot dry rocks. You have got to dig 3 kilometers deep are drilled into the earth first to find these hot underground radiogenic granite rocks. At this time, some Australia companies are exploring this technology.

If you were going to compare the amount of energy collected from geothermal to solar, you continue to get more from the sun. Notwithstanding that, people should still use it since solar energy cannot be harnessed when the clouds block the sun’s rays from reaching the solar panels.

Geothermal energy is a green energy source just like wind, hydropower and biofuel because it's a replaceable. By maximizing its potential, we don’t have to worry about the price of oil in the world market when it hit more than $110 a barrel and is now under $40 in the world market.

But that is not the only thing we should be concerned about. We also should do our best to defend the environment given that coal fired and nuclear power plants produce dangerous gases and radioactive waste that can cause to folk and the neighboring areas.

Everybody knows that our planet has changed due to global temperature rises. We learned our lessons from Chernobyl and 3 Mile Island but this does not necessarily mean it might not occur again.

For us to do our share to defend the environment now and for generations to come, we need to promote alternative energy and geothermal as a green energy source is just one of many that is now available.

Water can power an auto? If you believe that's most unlikely, well it is already here but this isn't yet being made on a commercial scale.

The German auto company BMW has produced the world’s first ever hydrogen powered automobile. While only 100 of these units were produced, you can already imagine if more of these cars are on the road.

The first model namely, the BMW Hydrogen 7 uses the body of the 760i model. Once you pop the hood, you will see the engine is dissimilar since it uses gas and hydrogen.

This just means we’ve not yet completely deserted our dependence on gas. Given more cash and time, the present 4.7 mpg it can travel using water alone could hit double digits in days to come.

The most important challenge to using water as a green energy source in contrast to oil in automobiles is the engine. While there are cars around like the Prius which runs on electricity and gas thanks to fuel cell technology, the hydrogen combustion is less than 10 years of age so you might say we are only seeing the tip of the iceberg.

To prevent the water from evaporating, this must be stored in a massive, 30-gallon, bi-layered and highly insulated tank so this doesn’t disperse into compressed gas. Another safety mechanism is the valves which are designed to open if the pressure in the tank exceeds 5 bars.

With the successfulness of the BMW H7, the company came out with a new automobile that is also partly powered by water known as the H2R. While we can’t yet put our garden hose into the fuselage to fill it up, this car uses liquid nitrogen as a fuel.

Tests on this car have shown it can achieve 285hp and reach a top cruising speed of 185.5 miles per hour. It can also accelerate from 0 to 60 mph under 6 seconds.

But why use water? It is really because hydrogen combustion is clean so it doesn’t emit damaging gases into the atmosphere unlike vehicles that run on petrol or diesel that emit carbon monoxide. Research has proven that it also weighs less than hydrocarbon-based fuels and burns quicker than typical gasoline.

So when can you be expecting to purchase a car that uses water as a home made energy source? Hopefully in the next 10 to 20 years. It is really up to the automakers because all we can do is wait until a better and cleaner vehicle hits the agency.

Right now, the best option we have are electric vehicles. Since its introduction in 1999, more people are using it because they don’t wish to spend anymore for petrol that would hit an all-time high of more than $110 per barrel.

If water as a green energy source may be used to power a car, why don’t we do the same for solar power which has been around much longer?

Sarah Green is an environmental campaigner, activist, and strong believer in making home made energy and being energy self-sufficient. In her spare time, she reports on DIY alternative energy blueprints and kits, such as the ben ford homemade energy download.

The employment of hydroelectric power or hydroelectricity dates back to Traditional Greece and China when they installed waterwheels in rapidly flowing streams to turn millstones and other gear. Years on, this was employed in the New World which is now known as Northern America to power saws and other kit.

But the hydroelectric plants of today still use the same elementary elements as the historical waterwheel with some adaptations. The difference is that we utilize the force of the power to push the turbine which powers a generator so generating electricity.

To make certain that there is a stable flow of power being produced, a dam needs to be built to retain the water. If there is a requirement for more power, the gates of the dam are opened so water can be released. During non-peak, the gates are closed. To guarantee there's water at all points, some dams have a recovery and pumping systems to the water released can be used again.

There are issues with the employment of hydroelectricity. Some claim that it poses a problem for fish and nautical plants on both sides of the dam. Because the flow of water has been altered, the nutrient rich silt which helps crops grow could be influenced which is precisely what occurred when the Aswan Dam was finished in Egypt.

But there are paths to fix that and the larger picture is that power produced from hydroelectric plants do not generate any emissions or waste which happens to be much better than operating a coal-fired power generation plant.

There's an alternative way to generate hydropower and you get this form the sea. This is also referred to as wave power or wave energy which uses changes in the air levels of sealed chambers to power turbines. When a wave rises into the chamber, the rise water pushes the air out which then turns a generator.

Once the wave goes down, air flows into the turbine and into the chamber through doors that will close.

These chambers remain floating on the ocean and how much power it produces varies. Plenty of these are used on the western coasts of Scotland, northwards Canada, southern Africa, Australia, and the northwestern coasts of the United States. These systems are usually tiny and can power a caution buoy or a little light house.

There's also tidal energy. The difference with wave energy is that when the tide approaches, the water is encircled in reservoirs behind dams. When the tide drops, the water behind the dam is released therefore making power like a hydroelectric power plant.

This could only work if you have tides that are at least 16 feet and because there are some places in the planet that may do that.

Finally, you have sea thermal energy. Here, you get power primarily based on the varied temperatures in the water. For this to work, you want at least 38 degrees Fahrenheit difference between the warmer surface water and the less warm deep ocean water. Still in the trial stage, it is employed Japan and Hawaii.

Hydropower is a green energy source. It is safe to use and what's even better is it is replaceable.

But what's bioenergy? Well, it's a process by which organic material such as animal waste, plants and wood are used to generate electricity, produce heat and also aid in the production of biofuels.

In the case of biomass, hot air or water is generated to provide electricity. This is done through direct combustion and is thought of as the simplest and commonest system of generating energy from biomass.

Except for generating electricity, biomass may be employed for hot air production so that you can keep a place warm. For this to work, biomass must be combusted in a furnace where it heats either water or air. Speaking of water, this helps you to have lukewarm water so that you can take a shower. Briefly biomass in itself can also be utilized in a small scale as a heating system.

Since you can create electricity and heat, some people have been able to mix the two which is sometimes known as combined heat and power or CHP. Something that many consider as good as you use one power source for 2 purposes.

If you can compare the quantity of electricity generated between biomass and let’s say solar power, you will notice that biomass produces more because the energy in plants is already captured and stored.

You don’t have to gather it first which is what happens with solar or maybe wind energy since this is manufactured technology. It is widely available not like the other two which is absolutely dependent on the weather.

Another is the incontrovertible fact that you can even use natural byproducts to product electricity. No other green energy source can do that and by using this extensively, any administration can economize as you don’t have to spend to dump the waste and you will no longer depend on foreign oil that much to power your plants.

The downside to biomass is that because you have got to burn waste and other organic materials to product power, you add to the pollution which is in the atmosphere. But this is offset naturally by planting more crops which we know helps cut the amount of carbon dioxide in the atmosphere.

You will additionally have to shell out a ton of money initially for the costs of labor, the transport of these fuels and how these should be stored.

Biomass uses replenish-able naturally occuring resources which explains why it is considered a green energy source. This means that we have a never ending supply of it around like the power of the sun or the wind which flows from the ocean. The challenge is to find suitable land that's got a enough water supply so these will be well placed to grow.

This indicates that in areas where water is not that abundant, you can't depend on biomass technology to generate electricity. When that happens, you use other means and one nice example given the right geographical location is wave energy which is the method of generating power from the water.

There is a way to create electricity without causing harm to the environment. We have the technology and the green energy sources. We just need to muster the willingness to make it happen.

Sarah Green is an environmental campaigner, activist, and robust believer in being energy self-sufficient. In her spare time, she reports on DIY alternative energy blueprints and kits, for example the ben ford home made energy download.

Take solar or wind energy as an example. We already know how to harness and make it. If you want to make one, perform some research online and then set up the system yourself.

To have solar electricity, you'll need to buy an inverter, battery, charge controller, solar panels, some wires and support structure. The sole difference with wind energy is that you need a fan. Once you have all that you need, you can put it all together.

If you are not skillful, you'll be delighted to know that some companies sell the whole system. By buying it from them and having it installed by their pros, you are positive that there will not be any issues the moment you switch it on.

There's one more thing you want before it is possible to use one or the two green energy sources. Before buying the materials or the system, make sure you have a flat area that is about a hundred sq. feet or so as it occupies lots of space.

For those that do not have the space or the budget to use these two energy sources, another possibility is to create your own biofuels.

Biofuels are used in many nations and they get it from harvesting corn, sugar and other crops. Fortunately , you do not need a farm to provide it because you can make your own using some recycled waste.

A nice example of this is plant oil which we use for cooking. To turn this into a biofuel, we first filter it by warming up the liquid and then filtering this with a coffee filter. The step after that is to get rid of the water also by boiling it again at 100 degrees for a brief period of time.

We need to know the amount of lye present in the plant oil and we do this by a process known as titration. When we are done with that, we now mix sodium hydroxide to provide sodium methoxide.

The method of converting used plant oil before it has a chance to become a biofuel takes quite awhile and it's got to be heated the entire time. This is done so the fuel we produce is pure and just when this is accomplished that we give it time to cool down.

Quite how much biofuel we make after all of the work varies but you will have an idea of how much you have produced since this is the one you see floating at the top. If there's still some glycerin present, filter it again. From there, you have already got your own backyard biofuel which you can use and even sell to those that are just as involved with the environment as you are.

By making our own green energy sources, we make ourselves less contingent on gasoline in its various forms to power our heater, home or auto. Why don?t a lot of people do it? Well just because they do not have the wherewithal to make it and would rather rely on someone else to do it for them.

Sarah Green is an environmental campaigner, activist, and powerful disciple of being energy self-sufficient. In her spare time, she reports on DIY alternative energy plans and kits,eg the ben ford homemade energy download.

Liquid biofuel which is the one used in cars is a natural and replenish-able domestic fuel that can only ever be utilised for diesel engines. This may be made from plant oils generally soy and corn. The great thing about it is that it contains no petrol, is harmless and bio-degradable.

By fueling up with biofuel, you decrease the contaminants in the air because it doesn’t emit anything. Right now, it's the only fuel accepted by the Environmental Protection Agency (EPA), passed every Heath-Effects Test of the Clean Air Act and meets the prerequisites of the California Air Resources Board (CARB).

One example of this is biodiesel which is made of alcohol like methanol and a chemical process that separates glycerine and methylesters (biodiesel) from fats or plant oils. Aside from methanol, some nations have also experimented with corn and sugarcane to form their own version of biofuel.

Glycerine is a standard product and this is utilized in making toothpaste and soap. Since it is sort of new, the process of converting it is quite pricey and at this time, this is still much dearer per gallon compared with petrol.

But if you look at what you pay for it, the returns are big because you get to do your part to preserve a cleaner environment, a difference in air quality and a reduction of cancer-causing agents.

A cheaper and primitive way to make bio-diesel is by collecting cooking oil and then processing it. This may harm your car’s engine so be careful if you decide to use it.

If you are skeptic about biodiesels, research has shown that its performance on the road is as good as petrol in terms of power to efficiency, hauling and climbing. You can use this in its pure form or blend with petrol fuel. The most common mix in the market is 20/80 and is known as B20.This suggests that 20% is biodiesel and the remainder is 80%. Another version is the E85 which is fuel composed of 85% ethanol and 15% petrol.

The best part about using biodiesel is that you only need to make a few changes in your engine to be well placed to use it. Apart from making the vehicle run, it can also help clean the engine. If you’re anxious this will void the guarantee of your vehicle should there be an issue, don’t worry because it doesn’t. In the US, B20 is the most typical one available but there are only a few gas stations that carry it.

When cars first rolled out in the beginning of the 20th century, Henry Ford planned to make these automobiles particularly the Model Ts run using ethanol. Tests have even shown that these may also run using peanut oil.

This never materialized because large oil deposits were discovered and diesel was cheap. It was only when our requirement for oil increased in the 1970s, 1980s, 1990s and in the early part of the current year that folk began to notice that to reduce our demand for foreign oil that we should try using biodiesels and other types of alternative energy.

Is it too late? Not yet because there is still plenty of time to use biofuels and others as green energy sources.

Sarah Green is an environmental campaigner, activist, and robust believer in home made energy and being self-sufficient. In her free time, she reports on DIY alternative energy blueprints and kits, for example the ben ford home made energy download.

But what do you have to make this work? A large amount of things but the 2 most important are the solar array and the batteries.

The solar array is vital because this is what’s used to gather solar rays and then converts this into electrical energy. There are 2 types to choose from in the market i. E the prefabricated type and the individual kind which you set up yourself.

When you are looking for branded parts, check out either Siemens or ASE Americas that sell terrestrial grade cells and the space grade cells. The low end model which can produce a significant quantity of power is the terrestrial grade version.

Proper wiring must be done to make certain that if one of the panels is not working, your vehicle will still move. If you're concerned that the voltage of the solar array should match the system voltage of your motor, you shouldn't to worry because it will still run.

We discussed earlier the battery is also important because here is where the solar energy will be stored. Your options for this are lead acid, lithium-ion or nickel-cadmium. Just how many you need to buy will rely on your motor’s voltage.

When you ultimately have these two parts, these will now have to be connected to the motor. So you know how much juice is left in your batteries, you will also need to install instrumentation similar to the warning display console on regular automobiles which tells you your speed, mileage and gas.

Remember to put a wheel, suspension, brakes, tires and hearts. You may not be able to make a vehicle that have the same features as like what you see done by one of the 3 US automakers but just about enough to be well placed to drive it from one place to the next.

The only autos that use solar energy so far are the ones only employed in races particularly the one held in Australia from travels from the northern part of the country all of the way to the south. If this has helped folk realize that renewable energy is actually the key to the future, the giant automakers should try drumming this technology instead of counting of still counting on gas.

But apart from solar energy as a green energy source, biodiesel is another choice. This is a mix of alcohol like methanol and a chemical process that separates glycerine and methyl esters (biodiesel) from fats or vegetable oils. This can also be done using corn and sugarcane.

Though these are not replaceable, these are still thought of as a green energy sources because it is cleaner than standard gasoline. This means you don't release harmful chemicals such as carbon monoxide into the air which causes damage to the environment. So if you can’t build a solar powered auto, consider a different fuel alternative.

Sarah Green is an environmental campaigner, activist, and robust disciple of being energy self-sufficient. In her free time, she reports on DIY alternative energy plans and kits,eg the homemade energy download by ben ford.

The benefit of using green energy sources is that it is clean so it doesn’t emit anything dangerous into the air which has a result on the environment. It is also replaceable which implies we will never run straight out of it unlike oil which is anticipated to dry up in 10 years or so.

Though green energy facilities are dear to build, it needs less upkeep so you don’t have to shell out lots of money to operate it.

It can also bring economic benefits to certain areas – even boost tourism.

While these sound good, there are some who say that there are benefits to using such technology.

While green energy sources can produce electricity, how much it can generate is not consistent. This is because we haven’t any control of the weather so if a certain area relies on solar energy and there is a weather rumpus, it will struggle to convert daylight into electricity.

Building these facilities also needs a lot of land so we might have to cut farmland which is what many are nervous about if more air turbines are going to be put up.

Another downside is the fact that some of the green energy sources can’t be installed in selected areas of the planet. For example, wave energy can only be utilised if the waves coming from the sea reach at least 16 feet. The use geothermal energy can only be done in geologically unstable parts of the planet.

But if you look at such arguments, places that cannot use one type of green energy source can be exchanged for another. If wind turbines need more space, they can be installed close to the coast instead of putting these on land. A study shows that you can produce more electricity while these are in the sea.

While the weather is a thing we cannot control, it isn’t everyday that there is a weather derangement so this too shall pass. If solar electricity is being used and the sun is covered, the emergency generators will be activated and use up the energy that was stored.

The point is just that there are ways round the discussions put by certain individuals which discourage the employment of green energy sources. In reality research is ongoing to try and harness alternative strategies with which to generate the power we need.

An excellent example of this is named ocean thermal energy. Power is generated by harnessing the different temperatures in the water. It is currently being used on a small scale both in Japan and Hawaii.

In America, only 7% of green energy sources are used nationally. This was way higher 11 years back and if we don’t have to stress about the cost of oil or even reduce our dependence on it, we must invest more in this clean energy.

We are able to get it from green energy sources like biomass, biodiesel, geothermal, solar, water and the wind. These are things we have all around us and all it takes is for someone to harness it rather than relying on standard non-renewable means to produce energy.

Breezy locations

Turbines get built in places that are gusty all the time, such as coasts and even the beaches of some massive lakes. The modern wind turbine has a high tower, at the top of which are two or three blades. The blades are moved by the wind. The kinetic energy is converted right into electricity by rotating a generator.

Wind turbine design

Wind turbines come in two basic designs, the fundamental difference being in the drive shaft. This is the part of the turbine that connects the blades to the generator. The most common design is the horizontal axis turbine, with two or three blades. Horizontal axis turbines have a horizontal drive shaft.

Vertical axis turbines have vertical drive shafts. The blades are lengthy, curved and attached to the tower at the very top and bottom. More recently, ‘shrouded ‘ air turbines have appeared. These have a hood around the rotor to funnel the wind over the blades. This leads to the wind to move faster over the blades, spinning them quicker.

Turbines are increasing in size, and the tallest are now more than 120 metres high. The wind is stronger higher above the ground, so taller turbines bring the blades into contact with quicker moving air. The blades are getting longer also , reaching lengths of 80 metres or more. They’re constructed from light, but powerful, composite materials, in order that they can survive strong winds.

The layout

The placing of the air turbines is important, too. If they’re placed too close together, they block the wind power from their neighbours. PCs are used to work out the best positions. Electronic monitors measure the wind speed and direction. This information is used to adjust the angle of the blades and the direction of the entire turbine to match the wind conditions. If the blades were allowed to spin too fast, they could break. If the wind is too strong, the blades are either turned out of the wind, or brakes are applied.

Fortunately, alternative power sources are growing in popularity. For example, locations with high water falls are experimenting with building hydro-electric energy generation plants and have been very successful. Other locations with high wind speed make use of wind turbines that may convert wind power into electricity

Solar energy is also one of the power sources that's gaining in popularity. Solar energy has continuously been growing. Today solar power is employed generally in the States and the advantages are numerous. Our solar energy source, the sun, its life-span is assessed to be another 4.5 bill years. It is fair to say this power source is nearly endless.

Good points and bad points of Solar Electricity

Just like every other kinds of energy resources, solar energy has its pros and cons.

Pros:

Pollution-free.
Solar facilities can be run with very little additional input or maintenance.
It is abundant. As mentioned earlier, most of the inhabited areas here on Earth can be reached by sunshine.

Cons:

Although it is limitless, non-tropical locations can receive limited daylight. So, power that'll be produced in these locations is a minimum.
Only available during daytime thus not available during night time.
Solar cell technologies generate direct current (DC) power which must be converted to alternating electric current (AC) power used in distribution grids.

Once worldwide development of the employment of cheap solar panels is materialized, we can expect that every household or industry in the world will now be powered by solar energy. It is not simply a dream, it's going to be a dream come true.
