Renewable Energy in the United States. Clean Energy News. Excluded from this definition is organic material that has been transformed over long periods of time by geological processes into substances such as coal or petroleum.
Several types of biomass can be used, with the proper technology and equipment, to produce energy. The most commonly used type of biomass is wood, either round wood or wood waste from industrial activities. Wood and wood waste can be combusted to produce heat used for industrial purposes, for space and water heating, or to produce steam for electricity generation.
Through anaerobic digestion, methane can be produced from solid landfill waste or other biomass materials such as sewage, manure and agricultural waste. Sugars can be extracted from agricultural crops and, through distillation, alcohols can be produced for use as transportation fuels.
As well, numerous other technologies exist or are being developed to take advantage of other biomass feedstock. With its large landmass and active forest and agricultural industries, Canada has access to large and diversified biomass resources that can be used for energy production.
Currently, bioenergy is the second most important form of renewable energy in Canada. Historically, the use of wood has been very important in Canada for space and water heating, as well as for cooking.
It is still important today, as 4. Every year, over petajoules of energy from wood are consumed in the residential sector, representing more than 7 per cent of residential energy use. The most important type of biomass in Canada is industrial wood waste, especially waste from the pulp and paper industry, which is used to produce electricity and steam.
Every year, more than petajoules of bioenergy are used in the industrial sector. The pulp and paper industry is by far the largest industrial user of bioenergy, which accounts for more than half of the energy used in this industry.
At the end of , Canada had 70 bioenergy power plants with a total installed capacity of 2, megawatts, and most of this capacity was built around the use of wood biomass and spent pulping liquor, as well as landfill gas.
In , 8. Most of the biomass-fired capacity was found in provinces with significant forestry activities: British Columbia, Ontario, Quebec, Alberta and New Brunswick.
Biofuels — or fuels from renewable sources — are a growing form of bioenergy in Canada. In , Canada accounted for 2 per cent of world biofuels production 5 th highest in the world after the United States, Brazil, the European Union and China. There are two main biofuel types produced in Canada: ethanol a gasoline substitute and biodiesel a diesel substitute.
The principal agriculture feedstock for producing ethanol, in Canada includes corn, wheat and barley. Canada is a major world producer and exporter of these grains. These main feedstock types used to produce biodiesel include vegetable oils, and non-edible waste greases and animal fats.
Based on Natural Resources Canada NRCan program estimates, Canada produced 1. The Government of Canada currently has several measures in place to support the production and use of renewable fuels:. There are provincial renewable fuel mandates in effect in the provinces of British Columbia, Alberta, Saskatchewan, Manitoba and Ontario.
British Columbia also has a Low Carbon Fuel Standard in place. The kinetic energy in wind can be converted into useful forms of energy such as mechanical energy or electricity.
Wind energy has been harnessed for centuries to propel sailing vessels and turn grist mills and water pumps. Today, wind is used increasingly to generate electricity. Wind energy is captured only when the wind speed is sufficient to move the turbine blades, but not in high winds when the turbine might be damaged if operated.
Canada has large areas with excellent wind resources and therefore a significant potential for the expansion of wind-generated power. Some of the highest quality areas are offshore and along coastlines. There are also high quality areas inland at different locations across Canada, including the southern Prairies and along the Gulf of St.
Installed wind power capacity in Canada has expanded rapidly in recent years and is forecasted to continue to grow at a rapid pace due to increased interest from electricity producers and governmental initiatives.
As of December 31, , Canada had over 5, wind turbines operating on wind farms for a total installed capacity of 9, megawatts, compared with only 60 wind turbines, 8 wind farms and 27 megawatts in The provincial leaders in wind power capacity are Ontario, Quebec, and Alberta. The bar chart displays installed wind power capacity in Canada since , in megawatts.
The bars of different heights show the rapid increase in capacity from 27 megawatts in to 9, megawatts in Solar energy is energy from the sun in the form of radiated heat and light. Historically, solar energy has been harnessed through passive solar technologies. Typically, these involve the strategic location of buildings and various elements of these buildings, such as windows, overhangs and thermal masses.
Such practices take advantage of the sun for lighting and space heating to significantly reduce the use of electrical or mechanical equipment. Solar energy can be harnessed only during the day and only if the sunlight is not blocked by clouds, buildings or other obstacles.
Today, two active solar technologies that involve electrical or mechanical equipment are becoming more common. First, solar collectors or panels are used to heat water or ventilation air for use in buildings.
Second, solar photovoltaic technology uses solar cells to convert sunlight directly into electricity. The potential for solar energy varies across Canada. The potential is lower in coastal areas, due to increased cloud coverage, and is higher in the central regions.
The solar potential varies even more around the globe. In general, many Canadian cities have a solar potential that is comparable internationally with that of many major cities. Installed capacity for solar thermal power has seen annual compound growth rate of The period was marked by the significant growth of installed capacity for solar photovoltaic power, which in , reached 1, megawatts of installed capacity.
In the first instance, geothermal energy can be captured from naturally occurring underground steam and be used to produce electricity. In the second instance, heating and cooling can be achieved by taking advantage of the temperature differential between outside air and the ground or groundwater.
The highest temperature geothermal resources are located in British Columbia, Northwest Territories, Yukon, and Alberta; heat and power generation projects are being considered with the demonstration projects under way. The South Meager project in British Columbia is the most advanced geothermal power project in Canada.
Furthermore, in , there were over 95, ground-source heat pumps representing about 1, megawatts of thermal energy MWth of installed capacity and producing an estimated 1, gigawatt hours equivalent annually. The ocean is a vast source of energy that can be harnessed to produce different forms of usable energy.
For instance, technologies have been developed to convert the energy of ocean waves and tides into electricity or other useful forms of power. However, a number of technical, economic and environmental barriers remain and, as a result, ocean energy is currently not a widely exploited energy source.
Renewable energy is energy Green Energy Sources from natural sources Metabolic health tips are replenished Energt a higher rate than they are consumed. Sunlight and Energj for Greeen, are such sources Green Energy Sources are constantly being replenished. Renewable energy sources are Green Energy Sources and all around us. Fossil fuels - coal, oil and gas - on the other hand, are non-renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide. Generating renewable energy creates far lower emissions than burning fossil fuels. Renewables are now cheaper in most countries, and generate three times more jobs than fossil fuels.
