Why we must embrace Renewable energy

The much fear energy crisis era is slowly but surely creeping up to us, fossil fuels and other non renewable energy cannot be depended upon for our future energy needs.

Non-renewable energy sources is depleting at an alarming rate. Renewable energy solutions refer to those energy solutions that can keep churning energy without exhausting the resources.

Three types of energy solutions fall into the category of renewable energy solutions: solar energy solutions, hydro energy solutions, and wind energy solutions.

Solar energy solutions: The sun’s energy is the most abundant energy available on earth. Make use of this free energy. You can employ solar power solutions at home. This will not only cut down power bills but also help you contribute to a greener world. Solar power solutions comprise of solar cookers, solar heating systems, solar lighting systems, solar dryers etc.

The sun has always been a source of heat energy and light energy. With the advancement of technology, the sun’s energy can be used to create other forms of energy.

The solar energy systems have many advantages apart from being cost-effective and environment-friendly. They are low on maintenance thus saving your time and effort. Also, solar systems give you a return on investment very soon, thus making the systems free after some time. Cooking with solar energy is also considered extremely healthy. Families have started employing solar energy as a power solution at their homes.

Hydro energy solutions: The hydro energy or water energy is an effective renewable energy. One can convert the hydro energy into electrical energy to run vehicles and various electrical appliances. Hydro energy is typically generated on a large scale. It has been estimated that 90 percent of the electrical energy produced by renewable resources is produced solely by hydro power. Dams are built to help generate electricity by tapping the water power.

There have been some concerns about using this energy because it is supposed to adversely affect the water-borne flora and fauna.

Wind energy solutions: Windmills were in existence even in the years before the birth of Christ. They helped tow boats and pump water. Eventually, post-industrialization, they became a source for generating electricity.

Windmills and wind turbines have never been passé. Wind energy can help generate tonnes of megawatts of electricity. When employed at individual estates, it can help do away with conventional power sources. An excellent renewable source of energy, the wind energy will go a long way in promising a good future to generations to come.

Alternative Energy is...

The entire earth is surrounded by energy, if we can harvest them efficiently then we will no longer have to rely on non renewable energy such as fossil derived fuels..

One of these alternative energy resources is wind power. Wind turbines continue to be developed that are progressively more energy efficient and less costly. Wind farms have been springing up in many nations, and they have even become more strategically placed over time so that they are not jeopardizing birds as former wind turbines did.

Another alternative energy resource is the one that is most well known: solar energy. This involves the manufacturing of solar cells which gather and focus the energy given off directly by the sun, and translate it into electricity or, in some cases, hot water. As with wind energy, solar energy creates absolutely zero pollution.

Ocean wave energy is seen by governments and investors as having enormous energy generating potential. A generator in France has been in operation for many years now and is considered to be a great success, and the Irish and Scots are running experimental facilities.

Hydroelectric power has been with us for a while and where it is set up, it is a powerful generator of electricity and cleaner than a grid. However, there are certain limitations to the availability of the right places to set up a large dam. Many run-of-the-river, or small and localized, hydroelectric generators have been set up in recent times due to this limitation.

Geothermal energy is extremely abundant, since it lies directly beneath our feet, just a few miles below the earth's surface. This energy is produced by the heating of water through the actions of earth's fantastically hot molten core. The water turns to steam, which can be harnessed and used to drive turbine engines which in turn generate electricity. Great amounts of research and development should be put into geothermal energy tapping.

Waste gas energies, which are essentially methane, reverse the usual energy-pollution relationship by creating energy from waste that lies in the dumps and from some air pollutants. This gas is used in fuel cells and can be used in standard gasoline generators.

Ethanol is a gasoline substitute and is created from such things as wheat, sugarcane, grapes, strawberries, corn, and even wood chips and wood cellulose. There is controversy over this fuel with regards to its ever becoming truly economical or practical except in very localized areas, but technologies for its extraction and admixturing are continuously being refined.

Biodiesel energy is created out of the oils contained in plants. So far, the commercial stores of biodiesel have been created using soybean, rapeseed, and sunflower oils. At the time of this writing, biodiesel is typically produced by entrepreneurial minded individuals or those who want to experiment with alternative energy, but commercial interest from companies is on the rise. It burns much cleaner than oil-based diesel.

Atomic energy is created in atomic energy plants using the process of nuclear fission. This energy is extremely efficient and can generate huge amounts of power. There is concern from some people about what to do with the relatively small amount of waste product atomic energy gives off, since it is radioactive and takes hundreds of years to decay into harmlessness.

What are the Advantages and Disadvantages of solar power

Perhaps the greatest argument that could be leveled about having to use fossil and nuclear fuel is our dependence on it. Global warming, though a real serious threat, maybe something that we could only be very worried about. Singly nothing much could be done about it as it will take serious political will if it is to be addressed effectively and for now, other countries are not cooperating. But the choice between traditional and alternative sources of energy, that is something most of us can choose to do.

First the advantages:

Solar energy is abundant and is free. We can count the sun to rise tomorrow and the day after that. Oil and natural gases on the other hand are non renewable, once the source taps out, it is gone forever. Sure there are other areas that could still be tapped but sooner that could run out of oil as well.

Solar energy does not pollute the air. If ever, the heat coming from the sun cleans the environment and maintains the earth's eco balance. Not so with oil. Oil, its derivatives and its byproducts are great pollutants. In fact, 22,000 pounds of carbon monoxide will need to be produced first for the oil to be processed and supply a home with electrical energy for a year.

Solar energy harnessing panels are silent operators. Except maybe for the mechanical contraptions that are built into the panels so it could track the sun, from the collection of the suns rays to its photovoltaic conversion, they give neither a peep nor a squeak. It is a world of difference from the cacophony of giant drills and pumps that are used to extract oil form the ground.

Maintenance for the solar panels is very minimal. Except for the mechanical parts that are optional, almost no maintenance is needed. Once it is installed nothing much will be the cause for worry. The energy that is derived is free. With oil there is no telling what the next pump price would be and when. Oil, being a commodity, heavily depend its prices on market forces. Often with the right strategies, even market forces could be manipulated that could cause volatility in pricing.

The Disadvantages of Solar Energy

The cost. While solar energy is free, the cost of installation setbacks many household from installing it. Brand new solar energy generating systems are expensive. Although it tends to pay off overtime, initial cash out could range into several thousands of dollars depending on the quality and volume of generated power a household or an establishment would require. While solar energy technology has been around since the 1950's it is only in recent years that its development was spurred. While costs of installation could also be subjective depending on the purchasing capacity of a customer, the benefits that could be derived out of it is enormous although mostly in unquantifiable terms.

For mass consumption, distribution lines are needed and this remains to be a big issue. Old antiquated distribution lines used to transfer electricity and other modes of fuel into the homes are clogged in many regions that to deliver solar energy power into the houses of consumers will require a different approach.

Be that as it may, the benefits from solar power far outweigh its disadvantages. It is an ideal source of energy that it may soon be the norm in power generation.

What are the sources Of Alternative Energy

The impending energy crisis is a hot topics in the political and economic cricle. Solutions are floating around that do not really address the problem at hand. I don't know about you, but I get overwhelmed and tired when I hear about the nearly endless amount of problems that threaten our environment each day. I am tired of hearing about global solutions that are aimed at making massive changes. Instead, I want to hear about the small changes that I as an individual can make that will help our energy crisis. So I've done a little research for your sake and mine, and I've come up with a few basic methods of alternative energy that almost anyone can follow.

First, and rather obvious, is to drive your car as little as possible. I hate hearing about solutions that are so unrealistic that they will never happen. You know as well as I do that we cannot all stop driving our cars every day. But maybe, just maybe, we can all look for small and simple ways to carpool and to cut down on the amount that we need to drive. Do you have a neighbor that works with you? If so, then contribute to alternative energy by carpooling and leaving one of the cars at home. Or even better, look for every chance to walk or ride a bike. I think we get caught up in all of the scientific terms about energy resourcing that we forget the most true source of alternative energy: ourselves. The more we can use our physical bodies, the better health we will be in and the more we will be contributing to the international effort to save energy.

Other simple methods of going for alternative energy are to shut off lights during the day and let the natural light of the sun brighten up your room or office. I cannot tell you how many homes and offices I have entered in the middle of the day that had lights blaring while the sun was beating in from outisde. So take a good look around you and see what extra lights and other appliances you have plugged in that you really don't need to use. The chances are high that everyone reading this has a few small ways that they could save energy each day.

Looking for various alternative energy sources is what will save the world. Like candlelight? Then consider using candles to light your room at night while you read. The world may not be changed by one more order from the government, but it just might be changed as individuals do their part in helping find and use methods of alternative energy.

Introduction to Solar Energy

Solar is definitely the energy of choice for the future. Producing electricity from solar is not rocket science. The process can be easily explain for the laymen to understand.

Solar cell, or more widely known as photovoltaic cell, collects energy from the Sun. A solar cell is a semiconductor device that is constructed using photovoltaic materials. It contains no liquids or chemicals, and no moving parts. Solar cells convert sunlight into electricity.

A solar panel generally consists of a series of individual cells, which are supported by a module that allows the cells to work in unison. The energy that is captured by the panel is stored in a battery. Solar panels generate direct current (DC) energy. Many solar energy systems have inverters in them which allow direct current (DC) electricity to be converted to alternating current (AC). Most consumer products such as appliances and electronics operate on AC current.

Unless you have a vast expanse of land to house an array of solar panels, it is unlikely that you will be able to power your entire home with solar energy. However, it is possible to power a single room in your house with a small array of panels fixed to the roof of your house. Multiply the wattage of each individual electrical device by the number of hours you expect to use them each day. That combined number will be your benchmark, or the bare minimum your system must be able to generate.

There are a number of options available to consumers that are considering converting to solar energy. A basic system that can be used to power a computer and a few other small items can be purchased for approximately $1000.00. Naturally, the price will increase with the production capacity of your system. In most regions, the price of an installed system will cost somewhere in the area of $10.00-$12.00 per watt.

Solar energy is one of a few truly renewable resources that can be used in energy and power generation. Every hour of every day, the Sun blankets our planet with enough energy to sustain our global energy needs for a year. As the technology behind photovoltaic energy advances, consumers will be unable to resist the urge to convert.

A lot of resources are being put into the development of solar energy technology. Most of the major oil and energy companies have entire divisions committed to solar energy. Researchers and engineers are spending countless hours trying to develop the technology today that will vastly improve conditions in the world tomorrow. It is no secret that we cannot continue down the path we are on. Fossil fuels are no longer a feasible option for energy production. The future is solar. The future is now.

Alternative Energy from renewable fuels

Germany have a head start in renewable energy sources and have become the major players in the alternative energy realm.

Under the aegis of the nation's electricity feed laws, the German people set a world record in 2006 by investing over $10 billion (US) in research, development, and implementation of wind turbines, biogas power plants, and solar collection cells. Germany's feed laws allow the German homeowners to connect to an electrical grid through some source of renewable energy and then sell back to the power company any excess energy produced at retail prices. This economic incentive has catapulted Germany into the number-one position among all nations with regards to the number of operational solar arrays, biogas plants, and wind turbines. The 50-terawatt hours of electricity produced by these renewable energy sources account for 10% of all of Germany's energy production per year. In 2006 alone, Germany installed 100,000 solar energy collection systems.

Over in the US, the BP corporation has established an Energy Biosciences Institute (EBI) to spearhead extensive new research and development efforts into clean burning renewable energy sources, most prominently biofuels for ground vehicles. BP's investment comes to $50 million (US) per year over the course of the next decade. This EBI will be physically located at the University of Illinois Urbana-Champaign. The University is in partnership with BP, and it will be responsible for research and development of new biofuel crops, biofuel-delivering agricultural systems, and machines to produce renewable fuels in liquid form for automobile consumption. The University will especially spearhead efforts in the field of genetic engineering with regard to creating the more advanced biofuel crops. The EBI will additionally have as a major focal point technological innovations for converting heavy hydrocarbons into pollution-free and highly efficient fuels.

Also in the US, the battle rages on between Congress and the Geothermal Energy Association (GEA). The GEA's Executive Director Karl Gawell has recently written to the Congress and the Department of Energy, the only way to ensure that DOE and OMB do not simply revert to their irrational insistence on terminating the geothermal research program is to schedule a congressional hearing specifically on geothermal energy, its potential, and the role of federal research. Furthermore, Gawell goes on to say that recent studies by the National Research Council, the Western Governors' Association Clean Energy Task Force and the Massachusetts Institute of Technology all support expanding geothermal research funding to develop the technology necessary to utilize this vast, untapped domestic renewable energy resource. Supporters of geothermal energy, such as this writer, are amazed at the minuscule amount of awareness that the public has about the huge benefits that research and development of the renewable alternative energy source would provide the US, both practically and economically. Geothermal energy is already less expensive to produce in terms of kilowatt-hours than the coal that the US keeps mining. Geothermal energy is readily available, sitting just a few miles below our feet and easily accessible through drilling. One company, Ormat, which is the third largest geothermal energy producer in the US and has plants in several different nations, is already a billion-dollar-per-year business geothermal energy is certainly economically viable.

Grants for Alternative Energy Research and development

Government, both at state and the federal level provide grants for the development of alternative technologies. If you are thinking of setting up a non profit organization or entity, the grants is a good source of fund to start up with.

Government grants for alternative energy research and development have been highly touted by politicians on local, state, and federal levels in recent years, all the way up to the President himself. This is due to the fact that we now recognize as a society that we need to seek out and develop alternative energy sources to those of the fossil fuels that we presently depend upon, as these fuels are not only slowly but surely running out (at least cheap access to digging them up is running out), but also damaging to the environment and air quality.

There is a fairly vast array of government grant programs available for you to check into. The great and most important thing to keep in mind about a government grant is that it's essentially free money. It is not a loan, you don't pay any interest, and you don't ever have to give the money back. However, qualifying for these grants, as you might imagine with something involving the government and free money, has quite a lot of restrictions attached to it. Not only is qualification based on purpose and need in the eyes and opinions of government bureaucrats, but just because you qualify does not mean that you necessarily get the grant. As Marshall McLuen put it, 搕he medium is the message? The fact of the matter is that it is typically easier to apply for and qualify to receive a business loan梑ut then, that would not be free money, that would be something you owed to someone, and with interest on top.

There are professional grant writers who know how to write proposals in such a way that they get around the heavy load of restrictions set up by the government, and you might need to resort to one of these. Even governments employ professional grant writers to seek money from other branches of the government, such as a country government needing funding from the state or the federal government. These people also keep abreast of what government grants are still or newly available and what ones have been removed from the table. It's an intricate web, so one must not get tangled up in when seeking needed financial backing for alternative energy research and development. In fact, it is so complex that in the last decade or so the ranks of profession writers, as both individuals and as entire companies, have swelled. It is a profitable business and this can make it fraught with illegal actions and controversial claims.

Nevertheless, each year there are many thousands of grants awarded throughout the United States for the purpose of helping the public. And again, with the government endorsement of grant money to be given to alternative energy researchers, you could very well get what you seek.
