The price of a barrel of oil never been higher ($ 62.00 + in summer 2005 even before the chaos by Katrina). Some say it is a temporary peak, but more and more analysts are agreed that such price is here to stay. Consumption World has reached a record level and given the new thirst for oil in China and India, it is unlikely to diminish. According to the International Energy Outlook, global demand should continue to increase by almost 59% in the next fifteen years.
Already, energy bills for consumers were growing on average by 6.5% per year over the last thirty years the United States. Given the dramatic increase in the cost production of energy using traditional non-renewable resources, this rate is bound to be overtaken by unheard-of price increases in very near future. And for consumers who are increasingly environmentally conscious, the thought of these millions and millions of tons of CO2 and other products bi be released into the atmosphere each year through the use of fossil fuels in creating energy very alarming.
It is obvious that our dependence on oil to create energy leaves us very vulnerable. There renewable technologies that produce energy, but the problem was one of cost effectiveness. It has always been cheaper to supply energy using fossil fuels and, consequently, renewable sources like solar or wind power have not departed. But the situation now seems to have changed. Increasingly, our energy consumption exceeds supply. The grid can hardly meet the demand and rolling blackouts are no longer just an idea. No government Wonder are looking for alternatives. And not everyone is an amazing talk time of more solar energy.
In 1985, annual worldwide solar power system represented 21 megawatts of electricity. In 2004, this had multiplied to an incredible 927 megawatts in new power generation for the single. The application of solar energy produced in recent years has increased annually about 25%, although in 2004 sales rose a huge 67% over the previous year.
There are several reasons for this increase in popularity for all things solar. Beyond the obvious considerations on the environment and the privilege of not having to rely on energy from a grid that is aging and stretched to capacity, solar energy becomes profitable. While energy production Traditional is more expensive, technological advances make solar power cheaper. In 1980, the cost of energy from the Harvest sun was about $ 100 per watt. Literally a hundred times more expensive than the going rate of electricity, these systems were not economically viable. In 1999 however, technology had reduced this to about $ 4 per watt and costs have continued to decline by about 5% per year since. The return on investment becomes very attractive for many commercial organizations and consumers.
Efficiency gains have been made in several technologies. The inverters that transform the data collected DC energy into usable AC energy used to provide approximately 65% efficiency. 35% of the collected energy was lost in the transformation process. Processors today are so effective they deliver up to 96% of the captured energy into usable AC current.
Photovoltaic technology has also made solar collection far more efficient. Twenty years ago, only 5% of sun energy hitting a solar charging has been harvested. This figure is now over 15% and will continue to climb as more efficient compounds are designed and introduced in the manufacture of these photovoltaic panels.
All levels of government seek more and more solar energy to supply stable, profitable and powerful environment. 35 states now have some sort of program rebates for homeowners who install solar energy systems. And not only the southern "sunny states". Then that California is the leader in promoting solar energy solutions (a program introduced in 2003 to promote the introduction of systems Solar Power, powered by one million homes over the next few years) New Jersey and New York is Next In Line for solar investment.
At the municipal level, several countries have introduced solar solutions for traffic and streetlights. 50% of the energy used to run the city of Sacramento Station Sewage water is solar. NASA uses solar energy in many systems of energy for its buildings. And governments using solar energy is not only because it is good for the environment and is an example for commercial entities and consumers (although these benefits may be lost to them!). They concluded that the choice for solar systems will save hundreds of thousands of dollars.
With so many discount programs many owners now come to similar conclusions. Once the initial return on investment is recovered (from 4 to 6 years with the rebate programs in California for example), users of solar energy have no bills additional energy, almost no maintenance to worry about and are not slaves to a power grid that is becoming increasingly fragile as demand outstrips supply. No wonder solar power is becoming the attention!
Solar energy is still more expensive than traditional energy production methods, but the gap is narrowing each year. The applications of solar energy growing at an astonishing pace. House heating, lighting and solar heating of swimming pools, hot water tank heating, calculators, flashlights, solar garden lighting and so on. Solar energy is clean, it is effective and it is here to stay.
