For centuries we have been using fossil fuels for industrial and domestic purposes. Most of us consider fossil fuels cheap. But now we are realizing the “real” costs of using fossil fuels. It is destroying our environment and making us pay in other terms. Another problem we are facing is, what were luxuries for [...]

Many homeowners today are looking into integrating green energy sources for developing more energy efficient homes and businesses.  A green energy source is power generated through renewable resources, such as the sun, wind and water.  The other benefit of green energy sources is their low contribution to global warming, pollution and other environmental issues.

The most popular of green energy sources is the sun.  Energy captured from the sun is called solar energy.  Of the green energy sources, solar energy is the most popular because it offers multiple options for use.  It is possible to harness electrical energy from the sun using solar panels consisting of photovoltaic cells that convert energy from the sun into electricity you can use in your home or business.  There are also solar hot water collectors that use the heat of the sun to produce hot water.  These solar green energy sources are readily available and increasing in popularity as most homes and businesses can have them mounted on their roof and they can take advantage of lowered utility costs.

The most efficient of green energy sources is wind.  Wind has been used to power water pumps for centuries, but has grown in popularity as a way to supplement home and business electricity needs.  Wind is the safest and cleanest of the green energy sources as it produces no pollutants and does not contribute to global warming.  Wind energy is harnessed by erecting a turbine that spins in the breeze generating electricity.  Unlike the sun, which can be found almost anywhere, in order to utilize wind as a green energy source, you must live in an area where wind is readily available.

Water is also a viable participant of green energy sources.  Water is less widely used as a green energy source for homes, as not all homes have an available stream to produce the needed electricity.  The Amish have used water to power entire shops using conveyer belt systems, so it is an old practice, but it is still being used successfully today.  As with solar and wind energy, energy harnessed from moving water is almost completely pollutant free and is generated from a renewable resource.

Green energy sources are available for use to combat global warming, our dependence on fossil fuels and to lower our monthly budget.  Investing in green energy sources for your home and business needs can add dollars to your wallet and years to the life of our Earth.

If you have been bogged by the enormous electricity bills you have been getting, it is time to take some concrete steps. You can reduce your electricity bills by following very simple steps.

This article will list some simple, easy-to-do things to reduce your electricity bill.

Limited use: Start with the room you are sitting in. If you were to take a call in another room or join your family at the dining table, would you just step out of your room without any concern for the electrical appliances in the room? If you would, stop right there, and look around. Switch off all the appliances even if you would be back in five minutes. Yes, even that will help. Every drop of water constitutes to the ocean.

Another thing to take care of here is what you perceive as an electronic appliance. Would you switch off the television set, turn off the fan, but not the light bulb? Yes, you need light, but not now when you are leaving the room. Taking care of these small things will go a long way in reducing the dreaded huge electricity bills.

Smart investments: Make some smart power investments by replacing your incandescent bulbs with compact fluorescent light (CFL) bulbs. These bulbs are a great power-saving investment.

Buy the Power Save gadget. The gadget helps monitor the power supply to your house and uses the minimum that is needed.

Home appliance usage: Most of us complain that the electricity bill touches the sky because of the number of electrical appliances they have at home. However, the electricity bill is not directly proportional to the number of gadgets you use but the way you use them. Let’s see how you can avoid the typical power-wasters.

• Use the washing machine only when there is a full load of clothes.

• Keep the geyser on for the minimal amount of time.

• Keep the air-conditioner at the minimum low or high temperature, just enough to keep you off the heat or the cold outside.

• Switch off the computer monitor even when you take a one-minute break. It takes just a second to switch on the monitor again!

Yeah, you have to stick to this way of life for saving power at home and for the world.

Remember, reducing your electricity bill is equivalent to saving power, thus helping the world save power for its future generations.

However, not all ethanol products are designed to be used as a kind of gasoline. The International Energy Agency (IEA) tells us that ethanol could comprise up to 10 percent of the world’s usable gasoline by 2025, and up to 30 percent by 2050. Today, the percentage figure is two percent.

Yet, we have a long way to go to refine and make economic and practical these biofuels that we are researching. A study by Oregon State University proves this. We have yet to develop biofuels that are as energy efficient as gasoline made from petroleum. Energy efficiency is the measure of how much usable energy for our needed purposes is derived from a certain amount of input energy. (Nothing that mankind has ever used has derived more energy from output than from what the needed input was. What has always been important is the conversion—the end-product energy is what is useful for our needs, while the input energy is just the effort it takes to produce the end-product.)

The OSU study found corn-derived ethanol to be only 20% energy efficient (gasoline made from petroleum is 75% energy efficient). Biodiesel fuel was recorded at 69% energy efficiency. However, the study did turn up one positive: cellulose-derived ethanol was charted at 85% efficiency, which is even higher than that of the fantastically efficient nuclear energy.

Recently, oil futures have been down again on the New York Stock Exchange, as analysts from several different countries are predicting a surge in biofuel availability which would offset the value of oil, dropping crude oil prices on the international market to $90 per barrel or thereabouts. The Chicago Stock Exchange has a grain futures market which is starting to “steal” investment activity away from the oil futures in NY, as investors are definitely expecting better profitability to start coming from biofuels. Indeed, it is predicted by a consensus of analysts that biofuels shall be supplying seven percent of the entire world’s transportation fuels by the year 2030. One certain energy markets analyst has said, growth in demand for diesel and gasoline may slow down dramatically, if the government subsidizes firms distributing biofuels and further pushes to promote the use of eco-friendly fuel.

There are several nations which are seriously involved in the development of biofuels.

Brazil, which happens to be the world’s biggest producer of ethanols derived from sugars, produces approximately three and a half billion gallons of ethanol per year. However, there are real concerns about deforestation and the implications for not only the wildlife, but also the effect on climate.

The United States, while being the world’s greatest oil-guzzler, is already the second largest producer of biofuels behind Brazil.

The European Union’s biodiesel production capacity is now in excess of four million (British) tonnes. 80 percent of the EU’s biodiesel fuels are derived from rapeseed oil; soybean oil and a marginal quantity of palm oil comprise the other 20 percent.

Germany’s “feed laws” permit 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.

As Remi Wilkinson, Senior Analyst with Carbon Free, puts it, inevitably, the growth of distributed generation will lead to the restructuring of the retail electricity market and the generation, transmission and distribution infrastructure. The power providers may have to diversify their business to make up for revenues lost through household energy micro-generation. She is referring to the conclusions by a group of UK analysts, herself included among them, who call themselves Carbon Free.

Carbon Free has been studying the ever-growing trend toward alternative energy-using homes in England and the West. This trend is being driven by ever-more government recommendation and sometimes backing of alternative energy research and development, the rising cost of oil and other fossil fuels, concern about environmental degradation, and desires to be energy independent. Carbon Free concludes that, assuming traditional energy prices remain at their current level or rise, microgeneration (meeting all of one’s home’s energy needs by installing alternative energy technology such as solar panels or wind turbines) will become to home energy supply what the Internet became to home communications and data gathering, and eventually this will have deep effects on the businesses of the existing energy supply companies.

Carbon Free’s analyses also show that energy companies themselves have jumped in on the game and seek to leverage microgeneration to their own advantage for opening up new markets for themselves. Carbon Free cites the example of electricity companies (in the UK) reporting that they are seriously researching and developing ideas for new geothermal energy facilities, as these companies see geothermal energy production as a highly profitable wave of the future. Another conclusion of Carbon Free is that solar energy hot water heating technology is an efficient technology for reducing home water heating costs in the long run, although it is initially quite expensive to install. However, solar power is not yet cost-effective for corporations, as they require too much in the way of specialized plumbing to implement solar energy hot water heating. Lastly, Carbon Free tells us that installing wind turbines is an efficient way of reducing home electricity costs, while also being more independent. However, again this is initially a very expensive thing to have installed, and companies would do well to begin slashing their prices on these devices or they could find themselves losing market share.
