Abstract-This study focuses on Nigeria energy resources and its consumption. .. Pdf>. Today the greatest attention in the world is devoted to energy resources because their use is usually irreversible, but the supplies of traditional fossil fuels (oil. Energy Scenario: Classification of Energy Sources, Energy resources ( Conventional energy sources are coal, oil, natural gas, and biomass (such as wood).
However, electrolysis still ranks below the previously mentioned methods for obtaining hydrogen, though research continues to make it more efficient and cost-effective.
Tidal Energy While tidal energy uses the power of water to generate energy, much like with hydroelectric methods, its application actually has more in common with wind turbines in many cases.
Though it is a fairly new technology, its potential is enormous. The most common form of tidal energy generation is the use of Tidal Stream Generators. These use the kinetic energy of the ocean to power turbines, without producing the waste of fossil fuels or being as susceptible to the elements as other forms of alternative energy.
Biomass Energy Biomass energy comes in a number of forms. Burning wood has been used for thousands of years to create heat, but more recent advancements have also seen waste, such as that in landfills, and alcohol products used for similar purposes. Focusing on burning wood, the heat generated can be equivalent to that of a central heating system.
Furthermore, the costs involved tend to be lower and the amount of carbon released by this kind of fuel falls below the amount released by fossil fuels.
However, there are a number of issues that you need to consider with these systems, especially if installed in the home.
Maintenance can be a factor, plus you may need to acquire permission from a local authority to install one. Wind Energy This form of energy generation has become increasingly popular in recent years. It offers much the same benefits that many other alternative fuel sources do in that it makes use of a renewable source and generates no waste. Current wind energy installations power roughly twenty million homes in the United States per year and that number is growing.
Most states in the nation now have some form of wind energy set-up and investment into the technology continues to grow. Unfortunately, this form of energy generation also presents challenges. Wind turbines restrict views and may be dangerous to some forms of wildlife. Geothermal Power At its most basic, geothermal power is about extracting energy from the ground around us.
It is growing increasingly popular, with the sector as a whole experiencing five percent growth in The World Bank currently estimates that around forty countries could meet most of their power demands using geothermal power. This power source has massive potential while doing little to disrupt the land. However, the heavy upfront costs of creating geothermal power plants has led to slower adoption than may have been expected for a fuel source with so much promise. Natural Gas Natural gas sources have been in use for a number of decades, but it is through the progression of compression techniques that it is becoming a more viable alternative energy source.
The production of algae to harvest oil for biofuels has not yet been undertaken on a commercial scale, but feasibility studies have been conducted to arrive at the above yield estimate.
In addition to its projected high yield, algaculture— unlike food crop-based biofuels — does not entail a decrease in food production, since it requires neither farmland nor fresh water. Many companies are pursuing algae bio-reactors for various purposes, including scaling up biofuels production to commercial levels.
SG Biofuels , a San Diego-based Jatropha developer, has used molecular breeding and biotechnology to produce elite hybrid seeds of Jatropha that show significant yield improvements over first generation varieties. It is considered sustainable because that thermal energy is constantly replenished.
Several entities, such as the National Renewable Energy Laboratory  and Sandia National Laboratories  are conducting research toward the goal of establishing a proven science around geothermal energy.
The International Centre for Geothermal Research IGC , a German geosciences research organization, is largely focused on geothermal energy development research. For example, biomass energy generation would have to increase 7-fold to supply current primary energy demand, and up to fold by given economic and energy growth projections. The remaining biomass is needed to maintain ecosystem functions and diversity. Windpower, if deployed on the large scale necessary to substitute fossil energy, is likely to face public resistance.
They also are often more expensive to develop per unit of energy and require a higher price to be economic. Research and investment into unconventional resources has increased significantly over the last two decades due to the higher price environment for oil and natural gas. In several cases, the technologies for economic production have already been developed, while in other cases, the resources are still in the research stage. What has qualified as "unconventional" is a complex and changing interplay of resource characteristics, the available exploration and production technologies and the current economic environment.
For example through the use of technology, oil resources such as the Bakken have been converted from previously uneconomic unconventional oil into proved reserves and production. The USGS estimates that there are 3 to 4. Other unconventional liquid hydrocarbons include production from oil sands, ultra-heavy oils, gas-to-liquids technologies, coal-to-liquids technologies, biofuel technologies, and shale oil.
Unconventional natural gas can be of several types. Today, tight gas, coalbed methane, and shale gas contribute significantly to U. Offshore and gas hydrates, ice-like solids in which water molecules form a cage-like molecular structure that traps methane represent an extremely large natural gas resource that requires additional research and technology development to be economically produced.
Unconventional natural gas resources represent an extremely large gas-in-place volume, and the U. With the addition of
