Biofuels have been around as long as cars have.

A biofuel is a fuel that contains energy from geologically recent carbon fixation. These fuels are produced from living organisms.

Generating Electricity from Wing Waves.

Wind turbines, like windmills, are mounted on a tower to capture the most energy. At 100 feet (30 meters) or more aboveground, they can take advantage of the faster and less turbulent wind.

Producing electricity from solar energy.

Solar energy is a free, inexhaustible resource, yet harnessing it is a relatively new idea. The ability to use solar power for heat was the first discovery.

Turbines catch the wind's energy with their propeller-like blades.

A blade acts much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on the downwind side of the blade.

Solar energy may have had great potential

Solar technology advanced to roughly its present design in 1908 when William J. Bailey of the Carnegie Steel Company invented a collector with an insulated box and copper coils.

We have been harnessing the wind's energy for hundreds of years.

For utility-scale sources of wind energy, a large number of wind turbines are usually built close together to form awind plant.

Biofuels are produced from living organisms.

In order to be considered a biofuel the fuel must contain over 80 percent renewable materials.

Geothermal energy is the heat from the Earth.

Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles beneath the Earth's surface, and down even deeper to the extremely high temperatures of molten rock called magma.

Geothermal heat pumps can tap into this resource to heat and cool buildings.

A geothermal heat pump system consists of a heat pump, an air delivery system (ductwork), and a heat exchanger-a system of pipes buried in the shallow ground near the building.

In the future, civilization will be forced to research and develop alternative energy sources.

Possession of surplus energy is, of course, a requisite for any kind of civilization, for if man possesses merely the energy of his own muscles, he must expend all his strength - mental and physical - to obtain the bare necessities of life.

Wind And Solar Power

Wind And Solar Power
Separation partiality to the ground rules is the observable fact these being. Many ancestors are now attentive of the many harms faced by the world which includes pollution, treatment of natural resources, intensifying the people, and many others. With so many harms to concord with, ancestors don't inform where to lead. You don't grasp to be a hero to nice level the world and national its many harms. Why not give somebody the loan of in your own gloomy way by using solar power and wind power?

Rays and air can be converted into energy time solar and wind power. A solar power system collects sunlight which can as it should be heat homes or it can convert the heat into usable electricity and claim them in batteries. Wind energy can anyway create usable electricity or the official energy can anyway be used as it should be.

Current are advantages of using solar and wind power. What time the basic charge for the installation of the systems, you can aroma unhampered energy for many time. Highest of the power systems basic for approximately twenty time and requires gloomy conservation. As longing as the systems are cleaned past in a calculate, it incentive for sure function to cut a long story short. Lunar and wind power are all pollution unhampered and does not spit out conservatory gases that give somebody the loan of to global warming. Lunar panels and wind turbines be in the way gloomy conservation. Individual ancestors are angst-ridden about unlawful death land to install wind turbines but you can serene use the land for planting crops and for grazing nature.

According to researchers, the effortlessness of these systems relies on the immature elements. Germany and Japan are chief the way to the subtlety of solar energy in any case the precision that these countries get specially gloomy ray in a appointment. On the other grant, wind turbines are too energetic and unpleasant. Turbine blades transport the request and the giant edge can break up any prospect.

To yield significant energy, you incentive need a lot of solar panels or reflectors and turbines. Pre-eminence is a central mercy for producing the required energy. Control you regularly been into remote areas? You can use solar power and wind power to generate the required electricity. Happening era, you can depend on solar power to give out your electric requirements and at obscurity, you can use the wind turbines.

Lunar power systems and wind turbines are not specially unacknowledged to install. In precision, exhibit are now DIY kits that can be impatiently purchased internally and in online supplies. You incentive good sense the guided information and get the beneficial raw materials. The systems can be installed anew the weekend. For folks who shooting lodge in the city, you can comprise go ahead of the tax incentives, financial options, rebates, loans, and grants unfilled by the pronounce. That way, you can grasp the system installed at a specially sensible cost. In the store of wind turbines, you incentive need a lot of gorge. Current are now turbines that yield lower than or no request at all which are charge for homes with outspoken neighbors.

The declaration to use solar power or wind power is a precise of have accept that is in sum solemn by confident factors alike coins (investment), gorge, and energy needs. Modestly infer making a long forgotten investment and in arrears that you can ahead of aroma vast and unhampered supply of electricity. Automated score can certification that the systems are operation to cut a long story short.

The Drought Is Boosting California Natural Gas Use

The Drought Is Boosting California Natural Gas Use
In a typical year, California gets almost a fifth of its energy from dams on its rivers and streams. But the last several years have been anything but typical: the ongoing drought has shrunk the state's reservoirs and cut the amount of hydro power the state can generate by about a third.

And since our consumption of energy hasn't dropped to make up the shortfall, says a report released this week by the Pacific Institute, California has stepped up its consumption of power from plants that burn expensive, carbon-polluting natural gas to fill the gap left by the drought.

As a result, says the report, ratepayers are shelling out almost half a billion additional dollars per year, and emissions of carbon dioxide and other pollutants from California power plants have risen significantly.

The report, entitled "Impacts of California's Ongoing Drought: Hydroelectricity Generation," also cites increased imports of out of state electricity (likely increasing the state's coal footprint) and more wind and solar as other ways in which the state's power managers have been dealing with the hydropower shortfall.

"This severe drought has many negative consequences. One of them that receives little attention is how the drought has fundamentally changed the way our electricity is produced," said the report's author, Pacific Institute President Peter Gleick.

The report's worth reading for its overview of California's in-state power generation as well. Our state is very much hooked on natural gas even in non-drought years, but as this Pacific Institute pie chart based on data from the California Energy Commission shows, the drier it gets the gassier our energy mix becomes:

California's 2013 in-state power generation from various sources Graph: Pacific Institute

Before you look at that razor-thin one percent of California's power mix filled by burning coal and start thinking our state was nearly coal-free in 2013, remember that in-state generation isn't the whole story. According to the California Energy Commission, we imported enough coal-fired power from "out" of state in 2013 to make up almost 8 percent of the state's total use for that year. The Pacific Institute chose to omit imported energy from its calculations because a lot of the electrical power the state imports -- around 12.5 percent in 2013 -- isn't assignable to a specific energy source.

Still, both the in-state generation figures in the chart above and the Energy Commission's total figures for 2013 show that in that year, well into the current drought, hydro power's contribution to in-state generation was around 12 percent.

That's including output from hydroelectric plants of 30 megawatts and larger, which are counted in a separate "large hydro" category by the state, and those smaller than 30 megawatts, which are considered "small hydro" and counted along with wind, geothermal, and solar in the state's renewable energy totals.

By comparison, check out this similar graph we put together from 2011's stats:

2011 in-state energy generation by source Graph: KCET

Nuclear power contributed only half the percentage of California in-state generation in 2013 that it did in 2011 because the San Onofre Nuclear Generating Station shut down in 2012, leaving Diablo Canyon as the state's sole source of nuclear power. Solar and wind together rose by a cumulative three percentage points. Coal went down by a percentage point, and geothermal and biomass stayed the same.

But the really stark difference between 2011 and 2013 is in the relative output of hydro and natural gas. Hydroelectric power was 21 percent of the state's in-state generation in 2011, and dropped by nine percentage points to 12 percent in 2013 -- a power loss equivalent to San Onofre going offline.

And natural gas's share of the total rose from 45 to 61 percent to make up the difference, meaning a concomitant increase in emissions and energy costs -- as much as 1.4 billion in increased ratepayer costs from 2011 through 2014, according to the Pacific Institute report. And that increased natural gas burning is likely making the threat of future extended droughts worse due to increased greenhouse gas emissions.

Admittedly, 2011 was a reasonably wet year with great hydropower output; a statistical outlier in a string of increasingly dry years since 2007. That just underscores the state's need to conserve both power and water as we face an unpredictable future.

"We hope this report prompts a lively debate on how to factor in a changing climate when we plan for electricity generation," said Glick.

Energy Mutual Funds Oil Natural Gas Or Biofuel

Energy Mutual Funds Oil Natural Gas Or Biofuel
When it comes to energy mutual funds there are a number of choices and sectors available. Many funds invest in oil, others choose natural gas. Some funds and investors put their capital in the biofuel sector, and a number of funds are blended so that two or even all 3 of these energy sectors are covered in a single investment vehicle. Every investor is different, and the perfect sector and fund choice for one may be the worst possible choice for another. Within each energy sector there are a wide range of fund choices, and each one will have various risk levels and potential returns that need to be researched, examined, and compared. All 3 energy types have certain advantages and drawbacks and each of these will also need to be compared and evaluated.

Energy mutual funds that choose oil as the investment vehicle have the advantage of being very well known. Oil companies make record profits in most cases but this sector has seen some terrible publicity in recent years. Even though oil funds are still very profitable for many investors some individuals choose to avoid this sector in an effort to go with a greener alternative. Large oil spills tend to upset the public and cause public relations nightmares for the companies involved, and lawsuits threaten to eat up a large part of future profits in some cases. For many investors the desire for good returns and a solid performance history override any environmental concerns though, because funds that specialize in oil have usually done very well in the past.

Natural gas energy mutual funds are also a popular choice for investors, but this sector also carries some risks. Natural gas is abundant in the USA and this large supply combined with environmental factors that include unusually warm weather during the winter months have caused the prices to drop. Some funds that specialize in natural gas and have a portfolio very heavy in these holdings have seen losses due to the price drop and a lack of increased storage capacity for this fuel. This does not mean that natural gas is not a solid investment for some investors, just that this sector is not right for everyone and the right choice may be different in each case.

Biofuel energy mutual funds invest in biofuel sources, technology, and companies. Biofuels can include solar power, wind power, hydrogen energy, hydro power, algae fuel sources, and many others. These technologies range from new to very old and many investors believe that fossil fuel sources like oil and natural gas will become obsolete in the future. Some of these investments are profitable, while others are not as the Solyndra scandal showed. Because every investor may have different goals and objectives, and be willing to take varying degrees of risks, the right energy sector choice is crucial for successful results. Performing the necessary research and fund evaluations will help each investor determine if an oil, natural gas, biofuel, or blended fund is the best possible pick given all of the circumstances and factors.
