Cool Ideas - Solar Energy

Global Warming is a big issue but the world currently needs oil to run. This can be chnaged if governments and people were willing to switch to alternative methods of energy production such as Solar Energy.

High lubricant Prices will make good for Renewables

1. Present high oil prices make life difficult in poorer countries but at the same time also help fuel development of renewable energy sources
   
2. There are several dilemmas regarding the high oil price.
   
3. It makes it difficult for the poor countries. At the same time renewable energy will be developed faster, which is good.

Higher Oil Prices Make Renewable Energy Living

Human Beings talk a more about alternative fuels being more Living with oil at such high prices. It also, however, makes other, more exotic, fossil fuel extraction techniques viable. This piece in the UK’s Independent outlines how oil reserves are understated because certain known fields are too expensive to extract at this time - and therefore are excluded from oil reserve projections (an important point that I would wager that many investors don’t understand).

The risk for green investors (and the environment for that matter) is that, if true, tapping oil reserves such as these could grow oil supply over current projections (even if its at these current high prices) - driving out the peak oil scenario longer than anticipated by Wall Street. (This is the kind of stuff investors and analysts miss all the time).

Emerging Oil Prices making Renewable Energy More Powerful

"Emerging fossil fuel prices are making renewable energy more involving in the global market"

Renewable energy can't offer much relief to drivers and companies seeing their profits evaporate because of skyrocketing oil prices, because viable green alternatives to gasoline are hard to find. Biofuels such as ethanol and biodiesel aren't widely available, and hydrogen-powered cars aren't expected to hit the market for years.

Price curves
But in the electricity market, green power, especially wind, is already competing with traditional sources. At today's average wholesale prices, wind costs 4.2 cents per kilowatt hour, compared with 4 cents for coal, 6.8 cents for natural gas, 9.1 cents for oil and 10 cents for nuclear power, according to Kyle Datta, managing director at the Rocky Mountain Institute, a research group focused on eco-friendly business.

Experts estimate that at today's consumption rates, known global supplies of oil and natural gas would be depleted within decades. But prices are expected to rise significantly long before supplies run out, making those fuels too expensive to use at current levels.

"They're never going to run out, but the ability to match supply to demand may already have run out, especially for oil," said Stephen Leeb, president of Leeb Capital Management and co-author of "The Oil Factor," which predicts that oil could hit $100 a barrel by 2010.

In the short term, fossil fuel prices are being driven up by war, political instability, natural disasters and other variables. The long-term outlook is clearer — global supplies are dwindling as demand soars, particularly in China and India, where automobiles are multiplying and economies are growing a breakneck speed.

"We should treat the prices as a warning that we need to act to promote energy efficiency and renewable energy," said Ralph Cavanagh, an energy expert at the Natural Resources Defense Council. "They represent a terrible threat to the vitality of the United States."

Meanwhile, improving technology, tax credits, low interest rates and government mandates are making renewables more widely available, establishing an inexhaustible energy supply that will keep driving prices down.

Different Kinds of Renewable Energy

• Solar energy which comes from the sun can be turned as electricity and heat. Solar panels on the roofs of houses, building and other establishment are use to store the solar energy. The sun's energy harnessed by the panels runs generators which provide electricity. There are stand-alone solar panels that you can put in your yard to save the sun's energy in a generator.
• Geothermal energy is an energy that comes from the heat inside the earth. It's simple technology that involves boring a hole into the ground to take the heat from the earth's crust. The heat that comes off is used to heat water and make steam to power generators to make electricity.
• Biomass energy is from the plant and trees. This energy alternative makes use of husks that come off rice after it is harvested and the waste from the corn. This "biomass" can be burned in a power station built for such a purpose. It emits less pollution than if the waste was left to rot, because it would produce a lot of methane.

Sources: Wood (most common source), plants, agricultural waste, industrial waste, even methane gas from community landfills.

Uses: fuel for transportation or to manufacture product that would otherwise use fossil fuels.

• Water Energy - the natural evaporation/precipitation cycle makes water a renewable source of energy. The heat of the sun causes water in lakes and ocean to evaporate and form clouds. The water then falls back to earth as rain or snow, and goes to the rivers and streams that flow back to the ocean. Moving water can be used to power water wheels that drive mechanical processes. Water Wheels are useful for generating mechanical energy to grind grain or saw wood, but are not practical for generating electricity because it is bulky and slow. Water energy emits about 30 times less greenhouse gas than modern natural gas power plants and 60 times less than coal-fired plant, which makes it a clean source of energy.
• Wind Energy is captured by wind turbines and used to generate electricity. The costs of wind energy are going down as mass manufacture of turbines becomes more accepted. It costs the same as setting up a new coal or nuclear power station. More importantly, external cost to health care and the effects of acid rain are 50times less than when using coal.

Renewable Energy - Benefits

The most obvious benefits of renewable energy are that it is far less polluting than conventional energy and will not run out. Renewable energy can also be produced more locally. This means that it can help local and national economies by using local resources and creating jobs. It will also help reduce the country’s dependence on overseas countries that may be politically unstable. This will help ensure supply and avoid price fluctuation.

Renewable energy is also much safer than nuclear energy which some people regard as ‘clean’. Accidents in nuclear plants can be catastrophic and there is the added problem of having to deal with nuclear waste.

One of the most important benefits of renewable energy is the fact that it’s non-polluting. And of course as the name tells us it is renewable and does not use resources that can never be replaced. Renewable energy has a much lower environmental impact than conventional sources of energy. But there are other advantages to using renewable sources of energy.

There are many benefits of renewable energy to the ordinary citizen and business owner. Homeowners will reap rewards from using renewable energy and energy-efficient appliances by saving money in the long run and reducing environmental impacts. It also renders us able to fuel our homes independently in many cases. Using renewable fuels makes us less dependent.

Benefits of Renewable Energy Source:

* Renewable energy sources offer clean alternative to fossil fuels.
* RE produces little or no pollution or greenhouse gases.
* RE will never run out
