Geothermal As An Alternative Energy Source

Tweet 

We have the technology to do plenty of things and one of those is to tap the earth’s energy. This is exactly what we do when we choose to use geothermal which happens to be a green energy source.

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

The downside to geothermal energy is the fact that it is dear to build. From the other perspective, as the earth’s crust continuously rots replenishing the heat, it still is a renewable power source.

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

Dry steam plants take steam out of fractures in the ground and use it to immediately 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 through a turbine to generate electricity.

Last, you have binary plants. Here, hot water flows thru 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 types of plants are injected into the hot rock to pick up more heat.

Geothermal plants are used operational in different parts of the globe. These are usually found in geologically unsteady parts of the planet. You can see some in Chile, Iceland, New Zealand, United States, the Philippines and Italy. At home, 2 most prominent areas for this are in the Yellowstone basin and in northerly California.

Except for digging deep into the earth, there are some who believe we will be able to create power from hot dry rocks. You have to dig 3 kilometers deep are drilled into the earth first to find these hot underground radiogenic granite rocks. Now, some Australia corporations are exploring this technology.

If you were going to compare the amount of energy picked up from geothermal to solar, you continue to get more from the sun. Regardless of that, folks should still use it since solar power can’t be harnessed when the clouds block the sun’s rays from reaching the solar cells.

Geothermal energy is a green energy source just like wind, hydropower and biofuel because it is a renewable. By maximising its potential, we don’t have to worry about the cost 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 isn’t the single thing we should be worried about. We should also do our best to protect the environment given that coal fired and nuclear power plants produce harmful gases and radioactive waste that can cause to folks and the neighboring areas.

Everyone knows that our world has changed due to global temperature rises. We learned our lessons from Chernobyl and 3 Mile Island but this doesn’t imply it might not occur again.

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

How Does Algae Production For Biodiesel Compare To Other Crops?

TweetMost of us have already felt the blow of the higher fuel prices and they are said to keep rising. With no increase in our income, this means that we either have to stop driving or we give up other things that we normally afford ourselves.

This doesn’t have to be the case. Algae biodiesel offers a very promising alternative to oil and is a resource that can theoretically never run out. That’s because algae is a plant that really only needs co2, water and sunlight to keep growing and multiplying. The water doesn’t even have to be clean.

To grow, algae need CO2, water, and sunlight. It is very unlikely that we will be running out of these resources anytime soon, if ever! So this makes algae biodiesel cheap and a long-term solution. You might be thinking, why algae and not any other plant.

Soybean is often cited as a great biofuel crop. In fact it’s one of the leading crops used for biodiesel blends right now. But the problem is that soybeans are a food crop. People and animals could eat it instead of converting it into biodiesel. This means that if you choose to grow soybeans for biodiesel, you will be taking away land from food production.

This issue is resolved by using algae biodiesel. Algae can grow in open ponds and in places where food production isn’t possible – for example in deserts and land not able to sustain agriculture. This means that creating algae biofuels does not take land away from food production.

Another advantage is that because the land is not good for much, it will be cheap to buy and allow the cost of algae biodiesel production to drop by a large amount. All that needs to be done is set up large water collections for the algae to grow in and they will thrive.

And when comparing the yield achieved between algae and soybeans the benefits become obvious. For example, if you take the same size of land and try to grow algae there and turn it into biodiesel and then you grow soybeans and turn that yield into biofuel, the result will be that the algae makes about 400% more than soy.

With our current algae biodiesel technology you could produce two thousand gallons of algae biodiesel each year from about one hectare of barren land. And this figure will continue to rise each year due to better understanding of algae production for biodiesel and more advanced technology.

Such large amounts of biodiesel are not needed by the average person. And because algae biodiesel uses little land it is now possible for people to start growing their own algae at home and converting it into biodiesel.

This can’t be done without the right knowledge and it isn’t the easiest thing to do. But by reading the right books and gaining the needed knowledge this can be done. It is possible to have the whole system set up and running for very little money because the equipment needed is very simple and cheap to acquire.

Making algae biodiesel at home is definitely the cheapest way to produce algae biofuels but if you don’t think that it’s not something for you then look for companies already making biodiesel locally. There are many lists online, so you just have to take the time and visit each facility to make sure their algae biodiesel is of good quality.

Home Energy Saving Tips – Going Green

TweetWhen shopping for new appliances, choose the ones where the energy star rating is in the most efficient range. Even if you cannot afford new appliances, you can choose new parts for your old appliances that are much more efficient and will help your old appliances save money and energy like new ones.

Make use of fans inside the home. You can easily use floor fans or have a ceiling fan installed to increase airflow inside the home. You can use these even if you already have an air conditioner because you can turn the thermostat higher and just use the fans for air movement.

If your exhaust fans are more than five years old, consider replacing them with newer more efficient models. Each year you should examine each exhaust fan in your home for damage and replace the filter. A damaged exhaust fan uses more energy and changing the filter allows the fan to work more efficiently.

Measure the prevailing wind speed on your property before considering a wind generator. In order for wind energy to be cost-effective, you need a wind speed greater than 8.5 to 9 MPH at least sixty percent of the time. Any slower, and the turbine won’t spin fast enough to generate much electricity.

Plant trees around your home. The trees will help provide shading for you home and therefore will help keep your home cooler in the hot summer months. It will not require as much air conditioning to keep it at your desired temperature. Since trees lose leaves in the winter, they will still allow the sun to come in and help heat your home during the winter months.

A wind turbine could help you cut down your electric bill by as much as 90%. Before you invest in this type of equipment, find out if the wind is strong enough to produce the amount of energy you need and get a professional to help you choose the right size of turbine.

Instead of using your air conditioner in the summer, try to wear fabrics that are natural. Fabrics like cotton naturally draw moisture away from the skin, allowing it to stay cooler. Wear lighter colors, as warmer colors make you feel warmer and more likely to put on artificial cold air.

Is Biomass An Alternative Energy Source?

Tweet 

Is biomass a green energy source? According to pros, yes it is. In fact , it’s one of the 3 important areas of bioenergy.

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

In the case of biomass, hot air or water is generated to supply electricity. This is done through direct combustion and is thought of as the simplest and most typical method of generating power from biomass.

Aside from creating electricity, biomass may be employed for hot air production so that you can keep a place warm. For this to work, biomass needs to be combusted in a furnace where it heats either water or air. Talking of water, this enables you to have lukewarm water so that you can take a shower. In short , biomass in itself can also be utilized in a little scale as a heating system.

Since you can generate power and heat, some people have managed to blend the 2 which is known as combined heat and power or CHP. Something that many consider to be good as you use one energy source for 2 purposes.

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

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

Another is the incontrovertible fact that you can also use organic waste to product electricity. No other green energy source can do that and by employing this at length, any government can save cash because you don’t have to spend to dispose of the waste and you won’t rely on foreign oil that much to drive your plants.

The downside to biomass is that because you have to burn waste and other organic materials to product power, you add to the pollution which is in the atmosphere. But this can be offset of course by planting more crops which we know helps cut the amount of CO2 in the atmosphere.

You will additionally have to shell out a lot of money at first for the costs of work, the transport of these fuels and how these should be stored.

Biomass uses replaceable natural resources which explains why it is regarded as a green energy source. This means that we have an endless supply of it around just like the solar energy or the wind which flows from the sea. The challenge is to find acceptable land that has a sufficient water supply so these will be well placed to grow.

This indicates that in areas where water isn’t that abundant, you cannot rely on biomass technology to generate power. When that occurs, you use other means and one excellent example given the right geographical location is wave energy which is the method of generating power from the water.

There’s a way to create power without causing damage to the environment. We’ve got the technology and the green energy sources. We just have to muster the eagerness to make it happen.

Why Is Hydropower An Alternative Energy Source?

TweetWhy is hydropower a green energy source? It is perhaps because we are able to harness electrical energy by changing water into electricity.

The use of hydroelectric power or hydroelectricity goes back to Ancient Greece and China when they installed waterwheels in speedily flowing rivers to turn millstones and other apparatus. Years after, this was employed in the New World which is now known as North America to power saws and other apparatus.

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

To make sure that there is a stable flow of power being produced, a dam has to be built to retain the water. If there is a need 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 is water at all points, some dams have a recovery and pumping systems to the water released may be employed again.

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

But there are methods 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 is an alternative way to generate hydropower and you get this form the ocean. This is also known 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 increase water pushes the air out which then turns a generator.

Once the wave goes down, air flows into the turbine and back into the chamber thru 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, northerly Canada, southern Africa, Australia, and the northwestern coasts of the United States. These systems are usually small and can power a warning buoy or a little light house.

There is also tidal energy. The difference with wave energy is that when the tide approaches, the water is trapped in reservoirs behind dams. When the tide drops, the water behind the dam is released so producing power similar to a hydroelectric power plant.

This can only work if you have tides that are at least 16 feet and as there are some places in the planet that will do that.

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

Hydropower is a green energy source. It is fine to use and what’s even better is it is renewable.

Alternative Energy

Article by Jerzy Jagielski

As the price of oil grows and the economy continues to stumble, the people realize that something must be done. What is that something? Well that something is turning our attention away from fossil fuels that are expensive and ruin the environment, towards some form of Alternative Energy that can, in the long run save the people money and help prevent mass pollution.To date, the United States is one of the largest users of fossil fuels in the world which has devastating effects of the environment. So of course a better form of energy must be found. Fortunately we don’t even need to look because Alternative Energy has been around for years. These different forms of Alternative Energy include wind, water, and sun. We could easily harvest the different forms of Alternative Energy that are seemingly endless in supply and help the fix the energy crisis as well as many of the world’s problems with pollution. Transitions to accommodate the harvest of this Alternative Energy may be expensive but the Wind Mills that would harvest wind power would pay for themselves in a matter of years, the Solar panels that would gather the sun’s rays would do the same and the hydro generators that are powered with water are in the same boat. These Alternative Energy sources are safe, healthy and after a few years they even become much cheaper than conventional fossil fuels since the supply would be constant and not depends on the demand of the populace. These forms of Alternative Energy help the world become a cleaner place for ourselves and brighten the future for generations to come.Contributing to the fight for Alternative Energy is simple. You can have solar panels installed, which although expensive can actually turn a profit in the long run, or if you cannot do that then write to your local senator or congressman demanding that legislation supporting the creation of Alternative Energy and significantly decreasing the dependence on fossil fuels be passed. They were elected by us, so they work for us. Make your voices heard!
