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).

Industrial biomass can be grown from numerous types of plants, including miscanthus , switchgrass , hemp , corn , poplar , willow , sorghum , sugarcane , bamboo , [99] and a variety of tree species, ranging from eucalyptus to oil palm palm oil.

Pollutants such as sulphurous oxides SOx , nitrous oxides NOx , and particulate matter PM are produced from this combustion. The World Health Organisation estimates that 7 million premature deaths are caused each year by air pollution, [] and biomass combustion is a major contributor of it.

Main article: Ethanol biofuels As the primary source of biofuels in North America, many organizations are conducting research in the area of ethanol production.

Much of this research is targeted toward the effect of ethanol production on domestic food markets.

It does not take away or directly conflict with the food supply because it is produced from wood, grasses, or non-edible parts of plants. 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.

Alternative energy

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. This form of energy generation has become increasingly popular in recent years.

Renewable Energy Sources

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. 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 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. In particular, it is being used in cars to reduce carbon emissions. Demand for this energy source has been increasing. In , the lower 48 states of the United States reached record levels of demand and consumption.

Despite this, natural gas does come with some issues. The potential for contamination is larger than with other alternative fuel sources and natural gas still emits greenhouse gases, even if the amount is lower than with fossil fuels. In contrast to biomass energy sources, biofuels make use of animal and plant life to create energy. In essence they are fuels that can be obtained from some form of organic matter. They are renewable in cases where plants are used , as these can be regrown on a yearly basis.

They accounted for approximately seven percent of transport fuel consumption as of Wave Energy Water again proves itself to be a valuable contributor to alternative energy fuel sources with wave energy converters. These hold an advantage over tidal energy sources because they can be placed in the ocean in various situations and locations.

Much like with tidal energy, the benefits come in the lack of waste produced. It is also more reliable than many other forms of alternative energy and has enormous potential when used properly.

Again, the cost of such systems is a major contributing factor to slow uptake.Unfortunately, this form of energy generation also presents challenges. However, the advancement of some of these technologies has been slowed down due to the amount of investment needed to make them viable. Sugarcane plantation to produce ethanol in Brazil A CHP power station using wood to supplies 30, households in France Biomass can be regarded as " biological material " [96] derived from living, or recently living organisms.

It creates a number of direct benefits in terms of emissions and efficiency, while also boosting the economy by creating jobs in plant creation and operation.

Although it took two decades to make this technology workable for normal oil and gas activities, DOE's long-term support was critical in the development of commercial tools for microseismic monitoring of fracturing procedures. 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.

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.

The largest portion of the unconventional gas produced today comes from the low permeability tight sandstone reservoirs of the Rocky Mountains. Though it is a fairly new technology, its potential is enormous. Conversion of biomass to biofuel can be achieved by different methods which are broadly classified into: thermal, chemical, and biochemical methods.

I do like upside-down. Feel free to read my other articles. I'm keen on tchoukball.
