Natural Energy Sources

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. Being landlocked only along its southern border, much of Canada is surrounded by oceans, meaning it has access to a significant energy potential.

Currently, Canada has a tidal power plant in Nova Scotia with a generating capacity of 20 megawatts of electricity. Tidal current technology demonstration projects have been deployed in British Columbia and Nova Scotia.

Over the next several years, roughly 13 megawatts of tidal current capacity is expected to be installed in the Bay of Fundy, Nova Scotia. You will not receive a reply. For enquiries, contact us. Content Key Descriptors What is Renewable Energy?

Hydro Energy Bioenergy Wind Energy Solar Energy Geothermal Energy Ocean Energy Key Descriptors Canada, with its large landmass and diversified geography, has substantial renewable resources that can be used to produce energy; these resources include moving water, wind, biomass, solar, geothermal, and ocean energy.

Renewable energy sources currently provide about Moving water is the most important renewable energy source in Canada, providing In fact, Canada is the second largest producer of hydroelectricity in the world. Wind is the second most important renewable energy source in Canada.

It accounts for 3. Wind and solar photovoltaic energy are the fastest growing sources of electricity in Canada. What is Renewable Energy?

It has a spelling mistake. Information is missing. Information is outdated or wrong. I can't find what I'm looking for. While hydropower is theoretically a clean energy source replenished by rain and snow, it also has several drawbacks.

Large dams can disrupt river ecosystems and surrounding communities, harming wildlife, and displacing residents. Hydropower generation is vulnerable to silt buildup, which can compromise capacity and harm equipment.

Drought can also cause problems. In the western U. Even hydropower at full capacity bears its own emissions problems, as decaying organic material in reservoirs releases methane.

Dams aren't the only way to use water for power: Tidal and wave energy projects around the world aim to capture the ocean's natural rhythms.

Marine energy projects currently generate an estimated megawatts of power—less than one percent of all renewables—but the potential is far greater.

Wind: Harnessing the wind as a source of energy started more than 7, years ago. Now, electricity-generating wind turbines are proliferating around the globe, and China, the U. From to , cumulative wind capacity around the world increased to more than , megawatts from 23, megawatts—more than 22 fold.

Some people may object to how wind turbines look on the horizon and to how they sound, but wind energy, whose prices are declining, is proving too valuable a resource to deny. While most wind power comes from onshore turbines, offshore projects are appearing too, with the most in the United Kingdom and Germany.

The first U. offshore wind farm opened in in Rhode Island, and other offshore projects are gaining momentum. Solar: From home rooftops to utility-scale farms, solar power is reshaping energy markets around the world. In the decade from and the world's total installed energy capacity from photovoltaic panels increased a whopping 4, percent.

In addition to solar panels, which convert the sun's light to electricity, concentrating solar power CSP plants use mirrors to concentrate the sun's heat, deriving thermal energy instead. China, Japan, and the U.

are leading the solar transformation, but solar still has a long way to go, accounting for around just two percent of the total electricity generated in the U.

in Solar thermal energy is also being used worldwide for hot water, heating, and cooling. Biomass: Biomass energy includes biofuels, such as ethanol and biodiesel, wood, wood waste, biogas from landfills, and municipal solid waste. Like solar power, biomass is a flexible energy source, able to fuel vehicles, heat buildings, and produce electricity.

But biomass can raise thorny issues. Critics of corn-based ethanol, for example, say it competes with the food market for corn and supports the same harmful agricultural practices that have led to toxic algae blooms and other environmental hazards.

Similarly, debates have erupted over whether it's a good idea to ship wood pellets from U. forests over to Europe so that it can be burned for electricity. Meanwhile, scientists and companies are working on ways to more efficiently convert corn stover, wastewater sludge, and other biomass sources into energy, aiming to extract value from material that would otherwise go to waste.

On a large scale, underground reservoirs of steam and hot water can be tapped through wells that can go a two kilometers deep or more to generate electricity. On a smaller scale, some buildings have geothermal heat pumps that use temperature differences several meters below ground for heating and cooling.

Unlike solar and wind energy, geothermal energy is always available, but it has side effects that need to be managed, such as the rotten-egg smell that can accompany released hydrogen sulfide. Ways To Boost Renewable Energy Cities, states, and federal governments around the world are instituting policies aimed at increasing renewable energy.

At least 29 U. states have set renewable portfolio standards—policies that mandate a certain percentage of energy from renewable sources. More than cities worldwide now boast receiving at least 70 percent of their energy from renewable sources, and still others are making commitments to reach percent.

Other policies that could encourage renewable energy growth include carbon pricing, fuel economy standards, and building efficiency standards. Corporations are making a difference too, purchasing record amounts of renewable power in Wonder whether your state could ever be powered by percent renewables?

No matter where you live, scientist Mark Jacobson believes it's possible. That vision is laid out here , and while his analysis is not without critics , it punctuates a reality with which the world must now reckon.

Even without climate change, fossil fuels are a finite resource, and if we want our lease on the planet to be renewed, our energy will have to be renewable.

Types of renewable energy

The rate at which heat is removed is proportional to the velocity of the air. Combustion air is required for fire. Fire is easily adjusted by controlling fresh air intake. Pumping water by windmills was familiar to rural Americans early in this century.

Water About three-fourths of the Earth's surface is water. The natural cycle of water evaporation and precipitation created by the sun is a force needed to sustain life on Earth. Many forms of energy can be realized from this movement of water in its natural cycle. Below are a few examples: Electrical energy can be generated by the movement of water in different ways.

Hydro-Electric Dams hold water above its natural level creating a head pressure needed to power generators. Turbines have been designed to take advantage of the Mississippi River and the Gulf Stream.

Ocean Thermal gradients are the temperature difference between surface and deep waters. In some parts of the world, heat engines can be powered this way. Tidal power can harness ocean movement resulting from gravitational forces of the moon.

Dams can trap water to be released through turbines. Turbines that take advantage of water movement in both directions are more efficient. Cooling with water is possible by exposing it to the clear night sky where heat is given up by radiation. Ponds on flat roofs are used in this manner.

Heat can also be lost through evaporation. Water sprayed on roofs is beneficial even in humid areas, but more efficient in arid areas.

Caution should be used in areas of scarce water or drainage problems. Thermal Inertia is the stabilizing of temperatures by a large body of water. Coastal, riverfront, and lakefront cities are known for their milder climates and refreshing breezes.

The wind movement is generated by the temperature difference from water to land. The temperature difference between day and night is much greater on land than over water. That is one reason why Alexandria is warmer in the summer and colder in the winter than New Orleans. Thermal Storage by water is four times the capacity of concrete, brick or gravel.

Each gallon of water can hold Btus of thermal energy. The heat in water is fairly evenly distributed by convection. Cleaning water takes place through its movement.

This movement causes it to drop the heavier impurities and gives it greater exposure to the sun and air. Algae and micro-organisms which live in the water also help to clean it. Plants need water as part of their food supply.

Water can be retained in cisterns or ponds for landscaping and greenhouse use. Conservation of water is important because it takes more and more energy to clean water and move it to your building. Recycling of a fixed supply of water on, in, and around the Earth is a natural system.

It can change states from solid to liquid to gas. Gray water from your building can be reused before disposal. Earth Earth is an almost spherical body approximately 4, miles in radius. The center is occupied by a hot core 2, miles in radius which is surrounded by the 1, mile thick mantle.

The outer crust is only 5 to 25 miles thick. It is within a few inches above and below the ground surface that earth, air, and water mix in the presence of sunlight. Here phenomena or processes of chemistry, osmosis, transpiration, decay, transmutation, and regeneration take place.

We are absolutely dependent upon the workings within this fragile matrix. Fossil Fuels are formed and contained in the earth. They are a valuable energy source which is renewable only on an extremely protracted time scale measured in millions of years. Cooling and Heating can be used by the thermal lag between surface temperatures and those below ground.

At a depth of 15 feet below ground, the temperatures will be about three months behind the surface temperatures. In Lafayette, the average yearly deep ground temperature is around 68°F in the summer to 71°F in the winter. Insulation value can be given to the earth by tempering heat gains or losses through roofs, walls, and floors.

Water pipes in the ground below the frost line are protected from freezing temperatures. Earth forms can be designed to protect buildings from wind and other harsh weather conditions, or they can be formed to channel air into the building.

Geothermal energy is provided by subterranean movement of water in contact with the intense heat produced at the Earth's core.

This source can provide steam and hot water. Geopressure can be found deep in the ground. This pressure can move turbines to produce mechanical or electrical energy. Purification of water occurs as it percolates down through the soil where impurities are deposited.

This process is aided by aerobic and anaerobic bacteria in the soil that over time reduce most waste to a harmless state. Building Materials can be obtained from the Earth at the site without or with less of the expense of manufacturing and transporting them.

Stabilized earth, adobe blocks, rammed earth, earth floors, sod roofs, and mud surfacing are examples of on site, low cost building material potentials.

Vegetation It is important to understand the value of plant life on Earth. It is interesting that words plant and planet are so much alike. Photosynthesis takes place in the chlorophyll cells of green plants -- consuming carbon dioxide, producing carbohydrates, and freeing oxygen.

This relationship of sun and plants that created the biosphere around the Earth allows man and animals to survive. Biomass is the plant and animal material produced by photochemical reaction.

Fire, Heat and Light are the release of the sun's energy used in creating the wood when wood is burned. Free oxygen is added back by the chemical process during combustion.

Chemically, a wood fire is the reversal of nature's growth process but at a much greater speed. Care must be taken to provide complete combustion, otherwise pollutants will be released into the air.

Methane is a colorless, odorless, flammable gas which is formed by the decomposition of organic waste products of living organisms on Earth. Methane, the main component of natural gas, can be used as a heating fuel and for illumination.

In addition, its by-product can be used as fertilizer. Alcohol can be obtained by a fermentation process producing Ethanol or by a distillation process creating Methanol.

Renewable energy is energy from sources that are naturally replenishing but flow-limited; renewable resources are virtually inexhaustible in duration but limited in the amount of energy that is available per unit of time.

Until the mids, wood was the source of nearly all of the nation's energy needs for heating, cooking, and lighting. From the late s until today, fossil fuels—coal, petroleum, and natural gas—have been the primary sources of energy. Hydropower and wood were the most used renewable energy resources until the s.

Since then, U. energy consumption from biofuels, geothermal energy, solar energy, and wind energy have increased. Total U. renewable energy production and consumption reached record highs in energy consumption. electricity generation was from renewable energy sources.

Click to enlarge. Renewable energy can play an important role in U. energy security and in reducing greenhouse gas emissions.

Using renewable energy can help to reduce energy imports and reduce fossil fuel use, which is the largest source of U. carbon dioxide emissions. According to projections in the Annual Energy Outlook Reference case, U. renewable energy consumption will continue to increase through The Reference case generally assumes that current laws and regulations that affect the energy sector, including laws that have end dates, remain unchanged throughout the projection period.
