Enhanced geothermal systems (EGS), also sometimes called engineered geothermal systems, offer great potential for more than 100 GW of geothermal power which 40 times more than present geothermal power.

ultimately geothermal global resources amount to 50,000 times the energy of all oil and gas resources in the world.

Enhanced Geothermal Systems (EGS) – Often categorized under the antiquated term‘Hot Dry Rock,’ EGS is thought by several experts to refer to any resource that requires artificial stimulation. This includes resources that have to be fully engineered, or ones that produce hydrothermal fluid, but sub-commercially. Regarding the latter, one expert states that, ‘As we go further, there might be projects that require more and more stimulation.’ Although EGS technology is still young and many aspects remain unproven, several projects are currently underway. If EGS technology proves commercially successful, it is expected to allow significantly increased extension of and production from existing fields, as well as utilization of geothermal energy in previously implausible locations.

Future Of Geothermal Energy The future of geothermal energy depends on three factors: it's demand, supply and it's competitiveness among other renewable resources in terms of cost, availability, reliability etc.. Demand for geothermal energy is going to increase and increase with the increase in the population and extinction of other non-renewable sources. Moreover, today government also support the resources which are cleaner and do not spoil the environment. Supply of geothermal energy is limited and confined to certain areas only.

Like many renewable resources, geothermal resources need relatively high initial investments to access the heat, hot water and steam. But the geothermal "fuel" cost is predictable and stable. Fossil fuel supplies will increase in cost as reserves are exhausted. Fossil fuel supplies can be interrupted political disputes abroad. Renewable geothermal energy is a better long term investment.

Examples are the huge costs of global climate change; the health effects from ground level pollution of the air; future effects of pollution of water and land; military expenditures to protect petroleum sources and supply routes; and costs of safely storing radioactive waste for generations. Geothermal energy can already compete with the direct costs of conventional fuels in some locations and is a clean, indigenous, renewable resource without hidden external costs.

Estimates of the electricity generating potential of geothermal energy vary from 35 to 2,000 GW.[2] Current worldwide installed capacity is 10,715 megawatts (MW), with the largest capacity in the United States (3,086 MW),[3] Philippines, and Indonesia.

The coal powder mixes with hot air, which helps the coal burn more efficiently, and the mixture moves to the furnace. The burning coal heats water in a boiler, creating steam. Steam released from the boiler powers an engine called a turbine, transforming heat energy from burning coal into mechanical energy that spins the turbine engine. The spinning turbine is used to power a generator, a machine that turns mechanical energy into electric energy. This happens when magnets inside a copper coil in the generator spin.

Electricity-generating plants send out electricity using a transformer, which increases the voltage of the electricity based on the amount required and the distance it must travel. Voltages are often as high as 500,000 volts at this point.  Electricity flows along transmission lines to substation transformers. These transformers reduce the voltage for use in the local areas to be served.  From the substation transformers, electricity travels along distribution lines, which can be either above or below the ground, to cities and towns. Transformers once again reduce the voltage—this time to about 120 to 140 volts—for safe use inside homes and businesses. The delivery process is instantaneous. By the time you have flipped a switch to turn on a light, electricity has been delivered.

Geothermal Energy produces no pollution. There are virtually no greenhouse gases given off. There is no pollution.

What is geothermal energy? Simply put, it is energy from the Earth. Geo refers to the solid part of the Earth and thermal refers to heat energy. Anywhere the Earth's surface is in close proximity to magma or volcanic activity under or near the Earth's surface, we can harness the energy.

Science tells us that every square meter of the earth's surface, when exposed to direct sunlight, receives about 1000 watts (1 kilowatt) of energy from the sun's light.

The advantage of AC for distributing power over a distance is due to the ease of changing voltages using a transformer. Available power is the product of current × voltage at the load. For a given amount of powe

3. You cannot transport geothermal energy. I used to live in the coal region of Pennsylvania. For years coal trucks used to drive by our front door hauling Anthracite coal to home and industries.

4. There may be geothermal gases. Geothermal steam and hot water do contain naturally occurring traces of hydrogen sulfide (a gas that smells like rotten eggs) and other gases and chemicals that can be harmful in high concentrations.

Biomass fuel refers to anything that can either burn or decompose. Other terms are biomass energy or biofuel. The prefix "bio" refers to life.

Also utilizing the source of bioenergy reduces pollution, helps control carbon dioxide emissions ( Remember, plants take in CO2 which will offset emissions)

Solar Cells or photovoltaic cells convert sunlight directly into electricity. When energy from the sun comes in contact with the cell, electrons in the two different semiconductors absorb the energy and use it to move around, creating an electrical current.

In scientific terms, wind energy is the "force" of winds blowing across the earth’s surface ("Wind Energy"). Wind is caused by uneven heating on the earth’s surface. The equator region receives more heat than say, Antarctica.

That heat tries to move from hotter to colder regions. Wind energy was first harvested centuries ago, when early windmills were used to power millstones, pumps, and forges

The amount of kinetic energy within Earth's atmosphere is equal to about 10,000 trillion kilowatt-hours.

Just as solar, hydro and biomass energy has been utilized for thousands of years, hydrogen technology as a fuel source has also been known for over 150 years.

Hydrogen is a simple element - an atom with only one proton and one electron. It is also the most plentiful element in the universe. Despite its simplicity and abundance, hydrogen doesn't occur naturally as a gas on the Earth - it is always combined with other elements.

Water, for example, is a combination of hydrogen and oxygen. Hydrogen can be separated from hydrocarbons by applying heat, a process known as "reforming" hydrogen.

The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.

While the United States today gets barely 1 percent of its electricity from wind turbines, many experts are starting to think that figure could hit 20 percent.

Achieving that would require moving large amounts of power over long distances, from the windy, lightly populated plains in the middle of the country to the coasts where many people live.

"Biofuels" are transportation fuels like ethanol and biodiesel that are made from biomass materials.

Ethanol and biodiesel are usually more expensive than the fossil fuels that they replace, but they are also cleaner-burning fuels, producing fewer air pollutants.

What Is Ethanol? Ethanol is an alcohol fuel made from the sugars found in grains, such as:
