Renewable energy sources general news

2008-12-07T15:17:00.000-08:00

Finding alternative energy sources World Bank has decided to increase renewable energy sources. But renewable energy sources have their advantages, but also some disadvantages.
Renewable energy sources available to us, particularly solar energy, hydropower, geothermal, wind, biomass and oceans. More ordinary these advantages is that they are also sources of energy are not cool not pollute the air. One disadvantage is ordinary, it is not possible, large amounts of electricity that can be made from fossil fuels. How are the technologies and the last of them is also very high.
Solar energy is the energy of the sun. He has some advantages, since these systems are not simply in existing buildings and would have no impact on the territory. The natural control of solar radiation and is on everyday and no cloudy days.
Hydro use of water energy to produce energy and is the most reliable source of energy and can be extended.
Some disadvantages are ecology, not cause more problems downstream. Decomposing vegetation on the river bed could lead to an increase of methane, a greenhouse gas. The dams can also cause changes in the natural flow of water also affect the nature of the region. What is the water cooler and can release oxygen in water and the fish die, suddenly free of water for flooding.
The use of geothermal steam from the earth of the earth to produce electricity and the smallest surface with other types of power plants. It can continuously over a year. The disadvantages are inclined to the central site and accurate throws toxic chemicals and the heat of the earth, and has tried to prevent steam.
Wind energy use wind power. Wind turbines are large and the fields below can be used for agriculture. These plants are very easy to manage, even if they are also the people and wild birds.
The energy of the oceans is usually expensive and only need access to energy is 40 degrees Fahrenheit at a distance of the water temperature throughout the year.
The flow of energy from biomass is made of wood, agricultural and municipal waste. It helps to landfill, but the transport is expensive and affects the diversity of soils. But the process is very complex and must be simpler.

A Few Good Questions Climate and Energy

2008-12-07T15:07:00.000-08:00

Now that Obama is elected, is the question everyone asks is - what else? There is much curiosity about what he would do as president to address issues related clean energy and climate change.

The good news is that Obama has already undertaken serious steps to reduce greenhouse gas emissions and promoting the use of renewable energy sources. But there are still many questions to be answered. As a starting point, here the three articles that I ran across this week that are interesting questions about climate and energy policy.

• First, I saw the article in time to ask: "Is Obama energy plan is enough? This is an eye-opener. The question is - even if Obama is ready for large-scale action in the field of energy and climate change, its agenda is ambitious enough to the extent problems?

• Here is the related question of a recent article on the mill, which is a Magic Number? Oh, this is terrible. It is the ultimate safe level of carbon dioxide in the atmosphere. Many prominent scientists argues that the 350 parts per million (ppm). Unfortunately, we are already 380 ppm. According to the author, Joseph room, this is a World War II level of effort to stabilize the climate. (More about this here. No surprise: it would lead to a lot of energy from renewable sources.) Big question is - is the public ready for this kind of work?

• And here is a good description of the problem on Earth Dot blog, wonders where is the world Obama is' shock and Trance 'regime? Probably in the last 60 Minutes interview with Obama suggested that declining energy prices, the world is moving from the "shock" mode "trance", or self-complacency. He said that while energy consumption is still high on his agenda, even if there is not much political support for the kind of changes that are needed. (Here's another interview.) Author of this article wonders whether there is a Katrina-level climate event to wake us from our energy trance. EEK.

But back to the good news. Not only that Obama is committed to act on climate change, is also leaving the door open for better solutions to our biggest problems. Obama is a new website asking Americans to their best ideas on various political issues. So if you have anything to say about climate change and energy, check-out in the field of energy and the environment page and let your voice be heard

In Depth: Green Power in Utah

2008-12-07T15:05:00.000-08:00

Utah has more than 6300 sites, for solar energy, and 51 are for wind energy. But so far, only a few are used. What are some of the plans for the future of Utah in the image of green energy?

More and more people call Frank Naylor, the owner of Solar Power Company in Salt Lake, asking how they can do what they never have to pay an electricity bill again.

"The average home will probably be about $ 60,000 to $ 70,000-system to meet their needs," he said.

Yes, this is a bit much, in general, for people to go for a cheaper system with which to compensate for part of its electricity with Rocky Mountain Power. Naylor said that the demand for them has shot dramatically since last year, despite an average cost of $ 10,000.

"They (PGR) have an agenda, including an incentive, which is to encourage them to do so. The state of Utah has an incentive to him to do, and the federal government has an incentive," he said.

Ground was broken in a solar power plant in St. George, but not the ordinary use of solar collectors.

Utah Clean Energy executive director Sarah Wright said: "[With] the concentration of a solar system, you take over a court that reflects the reality. The sun reflected on it and heats up a tube that is in a fluid, and makes steam To a turbine. "

Wright said that these groups are cheaper than the regular group, but still very expensive. In fact, says the majority of renewable energy sources are more expensive than fossil fuels, but they said that the answer is to think big.

"If the magnitude and the whole world begins to enter the concentration of solar [power], the price of 16 cents per kilowatt-hour eight to 10 cents per kilowatt-hour," he said.

Besides the solar energy, new wind farms in Utah. It was only broken ground on a new wind farm in Milford, and state officials are looking at where else can be constructed.

"Out of 29 counties in Utah, there are 24 districts, a very good resource potential of wind energy," said Mary Ann Wright with the Utah Area Renewable Energy Task Force.

She said that she had even noticed the green energy in the oil and gas fields in the Uintah Basin. Said heat sources have been found, in order to generate superheated water to a depth of 14,000 feet.

Cool Earth is the increase in solar power generation

Imagine Jan. 1-megawatt solar power plant has nothing to do with the vast swath of PV panels or mirrored a decline in the arid desert environment, requiring new lines to the population center. Instead, the picture is a rolling, grass-clad area inhabited by 500 vertical poles, each with two 8-foot-wide balloon. While cows graze between the poles, the major recyclable plastic balloons, each with a mirrored inner surface, truss and concentrated solar cell, follow the sun transit through a small electric motor. A utility substation is nearby.

While balloons deployed throughout the country to collect solar energy is really a happy picture, CEO Rob Lamkin will argue that the real Serendipity launch of the company's technology is an important source. "Enough sunlight hits the earth in one hour to power in the world for a year. But flat panel PV installed is U.S. $ 8 to $ 9 a watt, while our prototype is U.S. $ 1/watt," he said.

By making use of cheap, abundant thin plastic film, as its primary technology component, Cool Earth, the problem can be avoided in the manufacture of PV is needed to generate enough solar energy to meet demand and reduce carbon. "The magnitude of the problem of energy in TERa-watt and now there are less than 10 GIGA watts of PV installed. Aquatech Amsterdam in that many coal-fired power plants in a few weeks," said Lamkin. "We need to ramp up to Sunday GIGA-watt, or we will lose. A lot of people have figured out that we do not have enough PV. We had an installation of 10 GIGA watts of PV every four days until 2030 for carbon neutrality. "
