Renewable Energy

Posted by admin on October 9, 2013 in Renewable Energy with 1 Comment

Renewable energy is energy that comes from resources which are continually replenished such as sunlight, wind, rain, tides, waves and geothermal heat. About 16% of global final energy consumption comes from renewable resources, with 10% of all energy from traditional biomass, mainly used for heating, and 3.4% from hydroelectricity. New renewables (small hydro, modern biomass, wind, solar, geothermal, and biofuels) accounted for another 3% and are growing very rapidly.[2] The share of renewables in electricity generation is around 19%, with 16% of electricity coming from hydroelectricity and 3% from new renewables.[2]

Wind power is growing at the rate of 30% annually, with a worldwide installed capacity of 282,482 megawatts (MW) at the end of 2012, and is widely used in Europe, Asia, and the United States. At the end of 2012 the photovoltaic (PV) capacity worldwide was 100,000 MW, and PV power stations are popular in Germany and Italy. Solar thermal power stations operate in the USA and Spain, and the largest of these is the 354 MW SEGS power plant in the Mojave Desert. The world’s largest geothermal power installation is The Geysers in California, with a rated capacity of 750 MW. Brazil has one of the largest renewable energy programs in the world, involving production of ethanol fuel from sugar cane, and ethanol now provides 18% of the country’s automotive fuel. Ethanol fuel is also widely available in the USA.

While many Renewable Energy projects are large-scale, renewable technologies are also suited to rural and remote areas, where energy is often crucial in human development.[3] As of 2011, small solar PV systems provide electricity to a few million households, and micro-hydro configured into mini-grids serves many more. Over 44 million households use biogas made in household-scale digesters for lighting and/or cooking, and more than 166 million households rely on a new generation of more-efficient biomass cookstoves.[4] United Nations’ Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity.[5]

Climate change concerns, coupled with high oil prices, peak oil, and increasing government support, are driving increasing renewable energy legislation, incentives and commercialization.[6] New government spending, regulation and policies helped the industry weather the global financial crisis better than many other sectors.[7] According to a 2011 projection by the International Energy Agency, solar power generators may produce most of the world’s electricity within 50 years, dramatically reducing the emissions of greenhouse gases that harm the environment.

What are some renewable energy systems? Purchase/installation/maintena… for a college?

Posted by admin on June 12, 2013 in Renewable Energy with 1 Comment

I need to know some renewable energy systems.

The purchase/installation/maintenance costs for a college. Any information would be GREAT!

Yes, this is my college paper and I am having a hard time so I ask intelligent, smart people here in Yahoo Answers to help me out please. Thank you to all that try to help me.

Renewable energy comes directly from natural resources that can be constantly replenished such as wind, sun, wave and water. It is all around us, it’s just a matter of harnessing it. When it comes to using renewable energy, there are basically two options available. You can either buy a professional green energy system or you could start your own do it yourself renewable energy project. Buying a green source of energy system can cost you thousands of dollars but if you decide to start a do it yourself renewable power project you will only need to spend around $200 (If u are in United States).

If you are tend to purchase solar panel/wind turbine, you can do some research and find the minimum requirements needed and see if your residence is a candidate for solar or wind power or maybe a combination of both. Don’t forget to check with your local code enforcement officials for any restrictions or permits. You can ask the contractor you hired for the installation process and maintenance, but normally they don’t have a time to answer all of your questions.

On the other hand, if you prefer to build the system (solar panel/wind turbine) by your own, you can know all of the information you needed since you will learn step by step from the beginning until the end. It will also provide you the information regarding the maintenance of the system.

You can visit Mark’s website provided below to gather more information. He got lot of great stuff with regards Renewable Energy. Best of luck to you.

This Why We Need Alternative Energy Sources

Posted by admin on April 20, 2013 in Renewable Energy with 3 Comments

The need for alternative energy sources is getting urgent, hence the development of renewable energy is moving fast. Nationally and internationally various individuals and research companies are creating new and exciting energy systems. Some of these apparatus are great works and need improving for massive use. Politician’s world-wide are drafting policies and are making agreements to make greater use of these energy sources.

The first problem is that the fossil fuels are depleting in a rapid rate and are harder to retrieve. The consequence is that we can be facing an energy crisis in the future is we are not careful today. The energy prices will sky rocket and not be available for many individuals or countries. To avoid this doom scenario we need to find alternatives and used them to their full potential. Luckily this is already happening.

The second problem is that the fossil fuels that are widely used today are harmful for the environment. In the early seventies and eighties there were people and even scientist who preach otherwise, but today the negative effects are showing. The earth is warming up and climates are changing. There are parts in the world were there be more rain and sunshine and others parts will be come dryer then they already are. Another negative effect is that the ozone layer is getting thinner which also leads to a warming up of the earth. These two effects compliment each other and make it even more crucial to make another step in a different direction. This step will lead us to the use of Renewable Energy.

Another problem lies in the development of small economies. Because the energy prices for crude oil are going through the roof, these countries suffer even more. Many of these countries need crude oil for their electricity and means of transportation. These high oil prices have their effect on almost everything. The monthly electricity costs for households increase among others like transport cost and prices for basic products. Hence, these high oil prices make it harder for these small countries to grow there economies.

The solution for the above problems can be resolved by renewable energy. Our beautiful planet gives us the opportunity to make proper us of sunlight, flowing water, strong winds, and hot springs and convert these into energy. These energy sources are abundant and free to use. We must be sure that we convert the energy the right way, without causing other problems that can again hurt our environment. Luckily the many efforts by individuals and companies show that this can be done.

Solar energy or Renewable Energy can help you to save your electricity cost by 60% annually. A single house with 2 solar systems is sufficient for daily power usage. But the problem is a solar power system cost more than $1000. In this article I will show you the way of how you can get a home-made solar system for less than $200.

Earth 4 Energy is a website which offers a web-based program teaches how to build a home-made renewable energy generator. A solar power is enough to produce electricity for 3 heaters. It is also depend on the size of the solar plate. Each house should need at least a 2 kilowatt solar power system. The exceeding of electricity which isn’t use can be sold to a local power utility company.

2 meters are required to record the solar power which being used and another to record how much electricity did the solar system generated. As a result the electricity cost is less than $10 per month which reduces the utility expense by 60%. So you won’t have to worry about how much you have to pay for the bill. A solar system not only helps to keep the environment green but save a lot of money for you. As mentioned earlier, a solar system is costly. Earth 4 Energy is a D.I.Y. home-made solar system the program show you how to build a solar power device for less than $200. In fact you can buy parts from your local store or on the internet.

The program offers an instruction manual and videos show you how to build the system in detail. The process is explained in basic steps. The program is designed for people who have no basic knowledge about renewable power system and does not based on technical content. An experienced person can use the program for new ideas and tweak their skills. Earth 4 Energy offers a cost-effective way to build home-made renewable energy system for every household.

Let me show you how to successfully create a solar system for less than $200
