Why Use Biomass for Our Energy Needs

The last five years has seen a revolution in how governments, people and industry view energy. The positive aspects of biomass energy have come to the forefront in this discussion.

Why Use Biomass for Our Energy Needs: The Pros

The primary positive aspect of biomass is it is part of the biocycle of life. This means it isn’t toxic to the environment because it is more or less the environment. An additional benefit is the fact biomass almost always breaks down relatively quickly to its natural elements. This means a biomass fuel spill would be far less damaging than an oil spill, particularly in the long run.

The burning of biomass does kick out carbon dioxide among other gases. Carbon dioxide, of course, is a greenhouse gas. Proponents of biomass energy, however, argue that the gases produced are not really a problem because they are part of the current biocycle. By this, they are arguing that carbon dioxide is a natural element produced in nature and they are correct.

Fossil fuels, on the other hand, are outside of the natural biocycle in the world because they are buried in the ground, which effectively means they are not part of naturally occurring phases. As we dig and drill fossil fuels out of the ground, we are adding the harmful elements found in them to a system that cannot withstand the massive influx.

We already use many biomass fuels in our daily lives. The first cavemen used them to light fires for warmth, protection and cooking. Today, we use them to power our automobiles in the form of biodiesal and bioethanol. Whether you realize it or not, these two fuels have been going into our cars at gas stations since 1990 in parts of the country. The reason is they are used as additives in gasoline for the purpose of cutting harmful carbon dioxide emissions. In fact, federal law mandates their use in certain cities such as Los Angeles as well as in most government vehicles.

Carbon dioxide produced from vehicles makes up over a third of all the greenhouse gases produced in our country. Bioethanol made from corn cuts these emissions by over 20 percent compared to your basic gasoline. Biodiesel made from soybeans cuts emissions by as much as 80 percent. Any way you cut it, using biomass fuel is a step in the right direction.

An Overview of Biomass Energy

As fuel prices skyrocket, personal financial situations and entire economies are threatened. Biomass energy has been offered up as a possible solution.

An Overview of Biomass Energy

Energy can be produced in a number of ways. We can burn fossil fuels, use the sun's light for solar energy, use water for hydroelectric generators or even the heat of the Earth's core in geothermal energy. One often overlooked source of energy that belongs among all these others is biomass energy. Indeed, President Bush seems particular keen on the subject.

Biomass is biological (natural) material that was once living, or still is living, that can be used to produce energy. For example, lawn clippings, dead trees, unused crops, wood chips and other wood byproducts are all biomass. Even household trash can be considered biomass, as can “landfill gas”, produced when garbage decomposes in landfills.

Biomass energy is produced when these materials are burned as fuel to produce energy. Some biomass materials are burned to produce steam, which is then used with generators to produce energy and heat. Other biomass materials, such as landfill gas, ethanol (produced from corn and other leftover crops) and biodiesel (this fuel is made from leftover animal fats and vegetable oils) can be used to create biomass energy that can even power transportation vehicles.

While biomass energy should be used as frequently as possible, as the biomass fuels are readily available, this type of energy is often overlooked. Biomass energy only accounts for about three percent of the energy used yearly in the United States. Some people feel that using biomass for energy is not safe for the environment, or that they do not want a “garbage” burning power plant in their area. In fact, biomass energy is actually very safe for the environment – the only byproduct is carbon dioxide, which comes from the burning of any fuel. This greenhouse gas does have some harmful properties, but not near as many as the pollutants that are released with the burning of fossil fuels.

In order to see just what biomass energy can do for our world, society needs to become more open to the use of biomass as an energy source. Using discarded and waste products can help to reduce the amount of trash going into our landfills, as well as cut down on our need to use fossil fuels. This, in turn, will not only help the environment but also the world's economy. Biomass energy is an under-utilized energy source that needs to be fully researched and used in the years to come.

Hydro Energy for the Home

Can I really use hydro energy to power my home?

There are really very few people who would be able to take advantage of hydropower in their homes. A small stream simply isn’t going to be big enough to power even a micro hydro energy system but if you happen to be one of the very lucky few who have a reasonable size stream or waterway of any sort running through your land then hydro power is an excellent form of power and you should consider looking into it. It has one big advantage over any other sort of renewable energy you may be considering for your home. It will create power 24 hours a day, 7 days a week. The wind may stop blowing and the sun might stop shining but the water will always keep flowing. You can get hold of micro hydro turbines that will work with as little as 2 feet of water drop but still may provide you with enough power for the whole year.

Cover all your bases with wind and solar.

Combining this with a turbine and solar energy and you could probably power your neighbor’s houses too. Get a grid tie system which will enable you to buy energy from the grid and sell it back to the grid as well; you could be making a small profit as well as becoming completely energy self sufficient and doing your bit to beat global warming.

Finding a hydropower solution for your home.

There are fewer companies that deal with selling and fitting hydropower units simply because there is much less demand for it, but shop around you will be able to find one eventually. Find solar and wind energy companies and ask them if they do micro hydro generators as well; even if they don’t supply them themselves they may be able to put you in touch with a company who does. Calculate the drop you could get from the water as well as the average water flow so you can give them your measurements and they will be able to tell you what system is required and if it’s a viable solution, and if you find the right company they will probably come out and work that out for you.

Canyon Industries.

Canyon Industries Inc are manufacturers of micro hydro generators and are worth considering if you are serious about hydropower. You can visit their site at www.canyonindustriesinc.com and contact them for further information as well as for guidance on your waterflow.

Hydropower as a Clean Energy Platform

With carbon fuels under supply stress, hydropower presents one functional clean energy alternative. Here is an overview of hydropower and its practical application in modern society.

There are many different types of alternative energy available today. From solar panels to wind turbines to geothermal energy sources, the renewable energy field is exploding. Nations throughout the world are also coming up with their own ways of reducing usage of polluting and traditional energy sources, with clean hydro energy being a popular solution. Using water as an energy source has been around for ages. With the addition of modern technology, it has become a more efficient and useful resource for generating power for a hungry world.

Hydropower generates about 20 percent of the electricity generated in the world, making it the most widely used alternative energy source on Earth. In the United States, hydropower accounts for about 10 percent of the total electricity produced, which means the US produces the second highest amount of hydropower in the world after Canada. Norway, however, has both countries beat. Although it does not produce as much hydropower as it is a much smaller country, 99 percent of the electricity in the country is produced via clean hydro energy production. Another contender in the world’s best usage of hydropower contest is New Zealand, which produces 75 percent of the electricity in the country via clean hydro energy. Countries such as Brazil and Egypt are also heavily reliant on hydropower.

In the United States, 28 million homes are powered by electricity generated by hydropower. Unfortunately, only 2,400 of the 80,000 water dams in the country are being used to produce electricity. This is a rather alarming fact. If more of the dams were put to use creating power, we would be far less reliant on expensive, polluting, non-renewable carbon fuels such as coal, oil and natural gas. One can surmise that the process of converting the dams to hydropower production would be expensive, but the rising price of oil may soon make it a viable option.

Hydropower is a major player in the energy game. Frankly, it should be used even more where possible. Currently, the energy produced via hydropower production replaces the use of 22 billion gallons of oil each year. That is a significant number, but more may be about to come.

Although not a form of traditional hydropower, many are now looking to produce electricity from the oceans. Much like traditional dam turbines, companies and nations are now investigating if it is possible to put turbines in the ocean that are turned via moving currents and tides. The idea is fairly new, so a practical application is unlikely in the very near future. Nonetheless, if the process can be worked out, the energy worries will be greatly alleviated given the massive amount of energy in the ocean.

Compared to carbon fuels, hydropower is a very attractive way to meet our energy demands. Counties such as Norway and New Zealand prove it can be done with the proper planning.
