The Investment into Green Energy

In the United States, Canada and Australia both commercial and residential consumers can buy green energy from their standard local utility provider of from a provider that specializes in green energy. Many third party suppliers of energy provide green energy electricity that is produced from renewable resources. This energy is delivered to consumers by way of their local electric utility company. The consumer who opts for this green energy course pays a small premium each month on her or his utility bill as the additional cost of the green energy they are getting. The other option is to buy directly from the green energy supplier.

Of course, when a consumer buys the green energy via the local utility company he or she cannot know it’s really green energy in other words; they do not know that they truly got what they paid extra for. It is a matter of trust. The local electric company buys the electricity from the various producers. These can be nuclear, coal, hydroelectric power on a large scale or green energy providers such as solar and wind energy producers.

Must electricity from the local utility company in any country comes from fossil fuels or nuclear power that is not renewable and or pollutes the environment to a high and dangerous level. Green energy is the current provider of a minimal percentage of our world’s electricity. In fact, when utility companies buy green energy for the consumers that request it they generally only buy 25 percent of what they ultimately provide to all.

Consumers who sign up with their local utility provider to pay a premium each month for green energy are not only helping to save their environment but they are also sending a message to the utility companies and the legislature that they are willing to pay extra for healthy air for us all.

There are environmentally conscious, forward thinking countries such as the Netherlands that have committed themselves to matching their consumers’ purchase of green energy with an equal amount of green energy buy for governmental use. The government of Holland exempts green energy producers and users from its pollution tax. This exemption brings the cost of green energy consumption down considerably.

Several organizations in Europe promote the consumption of green energy, and there are a number of green energy providers, although the high cost of electricity in those countries has kept the use of the less expensive gas and oil the majority provider.

At work now are efforts to distribute cheap renewable electricity in these countries so the average electrical consumer can afford to support the environment and clean air efforts with the use of green energy products. Consumers can install their very own renewable green energy system, based locally.

This may be solar, wind or even water power. Geothermal heat pumps also provide green energy by tapping a few feet into the earth’s temperature.

Many U.S. states now offer monetary incentives for those who want to use the more costly green energy electricity sources.

What You Should Know Green Energy

Green energy refers to the use of power that is not only more efficient than fossil fuel but that is friendly to the environment as well. Green energy is generally defined as energy sources that don’t pollute and are renewable.

There are several categories of green energy. They are anaerobic digestion, wind power, geothermal power and hydropower on a small scale, biomass power, solar power and wave power. Waste incineration can even be a source of green energy.

Nuclear power plants claim that they produce green energy as well, though this source is fraught with controversy, as we all know. While nuclear energy may be sustainable, may be considered renewable and does not pollute the atmosphere while it is producing energy, its waste does pollute the biosphere as it is released.

The transport, mining and phases before and after production of nuclear energy does produce and release carbon dioxide and similar destructive greenhouse gases. When we read of green energy, therefore, we rarely see nuclear power included.

Those who support nuclear energy say that nuclear waste is not, in fact, released into our earths biosphere during its normal production cycle. They stress as well that the carbon dioxide that nuclear energy production releases is comparable, in terms of each kilowatt hour of electricity, to such sources of green energy as wind power.

As an example of the green energy production the average wind turbine, such as the one in Reading England, can produce enough energy daily to be the only energy source for 1000 households.

Many countries now offer household and commercial consumers to opt for total use of green energy. They do this one of two ways. Consumers can buy their electricity from a company that only uses renewable green energy technology, or they can buy from their general supplies such as the local utility company who then buys from green energy resources only as much of a supply as consumers pay for.

The latter is generally a more cost - efficient way of supplying a home or office with green energy, as the supplier can reap the economic benefits of a mass purchase. Green energy generally costs more per kilowatt hour than standard fossil fuel energy.

Consumers can also purchase green energy certificates, which are alternately referred to as green tags or green certificates. These are available in both Europe and the United States, and are the most convenient method for the average consumer to support green energy. More than 35 million European households and one million American households now buy these green energy certificates.

While green energy is a great step in the direction of keeping our environment healthy and our air as pollutant free as possible, it must be noted that no matter what the energy, it will negatively impact the environment to some extent.

Every energy source, green or otherwise, requires energy. The production of this energy will create pollution during its manufacture. Green energies impact is minimal, however.

Why Solar?

While a majority of the world's current electricity supply is generated from fossil fuels such as coal, oil and natural gas, these traditional energy sources face a number of challenges including rising prices, security concerns over dependence on imports from a limited number of countries which have significant fossil fuel supplies, and growing environmental concerns over the climate change risks associated with power generation using fossil fuels. As a result of these and other challenges facing traditional energy sources, governments, businesses and consumers are increasingly supporting the development of alternative energy sources and new technologies for electricity generation. Renewable energy sources such as solar, biomass, geothermal, hydroelectric and wind-power generation have emerged as potential alternatives which address some of these concerns. As opposed to fossil fuels, which draw on finite resources that may eventually become too expensive to retrieve, renewable energy sources are generally unlimited in availability.

Solar power generation has emerged as one of the most rapidly growing renewable sources of electricity. Solar power generation has several advantages over other forms of electricity generation:

Reduced Dependence on Fossil Fuels: Solar energy production does not require fossil fuels and is therefore less dependent on this limited and expensive natural resource. Although there is variability in the amount and timing of sunlight over the day, season and year, a properly sized and configured system can be designed to be highly reliable while providing long-term, fixed price electricity supply.

Environmental Advantages: Solar power production generates electricity with a limited impact on the environment as compared to other forms of electricity production.

Matching Peak Time Output with Peak Time Demand: Solar energy can effectively supplement electricity supply from an electricity transmission grid, such as when electricity demand peaks in the summer

Modularity and Scalability: As the size and generating capacity of a solar system are a function of the number of solar modules installed, applications of solar technology are readily scalable and versatile.

Flexible Locations: Solar power production facilities can be installed at the customer site which reduces required investments in production and transportation infrastructure.
