Clean energy is energy gained from sources that do not release air pollutants, while green energy is energy derived from natural sources. There is a subtle difference between these two energy types even though they are often spoken of as being the same.
Renewable energy is power generated from sources that are constantly being replenished. However, while most green energy sources are renewable, not all renewable energy sources are seen as being green. For example, hydropower is a renewable resource, but some would argue that it is not green, since the deforestation and industrialisation related to the building of hydro dams can damage the environment.
The perfect clean energy mix occurs where green energy meets renewable energy, such as with solar energy and wind energy. Clean energy works by producing power without having negative environmental impacts, such as the release of greenhouse gases like carbon dioxide. A lot of clean energy is also renewable, including wind power, some hydro resources and solar powered energy generation.
The most important aspect of clean energy are the environmental benefits as part of a global energy future. With fuel diversification, through different power plants using different energy sources, it is possible to create reliable power supplies to enhance energy security, ensuring there is enough to meet our demands.
Clean energy provides a variety of environmental and economic benefits, including a reduction in air pollution. A diverse clean energy supply also reduces the dependence on imported fuels and the associated financial and environmental costs this incurs. Renewable clean energy also has inherent cost savings, as there is no need to extract and transport fuels, such as with oil or coal, as the resources replenish themselves naturally.
Other industrial benefits of a clean energy mix is the creation of jobs to develop, manufacture and install the clean energy resources of the future. Clean energy can be used for a variety of different applications, from electricity generation to heating water and more, depending on the source of the energy.
Solar energy can be used for heating and lighting buildings, generating electricity, heating water directly, cooling and more.
Solar panels allow for energy from the sun to be collected and turned into electricity. Solar panels are frequently used for small electric tasks, such as charging batteries, while many people already use solar energy for small garden lanterns. However, this same clean energy technology can be scaled up to larger panels that are used to provide power for homes or other buildings or even installations of multiple solar panels, such as with a community solar panel array to power entire towns.
Water is another clean resource with some surprising applications. Most obvious are hydroelectric power plants, which take the flow of water from rivers, streams or lakes to create electricity. A less obvious use of water comes through municipal pipes in towns and cities.
With lots of water running through pipes in homes each day, there is a move towards harnessing this energy to help meet domestic and other power needs.
As generators become smaller and less expensive to build this use of municipal water is becoming closer to being a daily reality. Wind power works by attaching a windmill to a generator which turns the turning of the windmill blades into power.
This form of energy has been used for centuries to grind grain, pump water or perform other mechanical tasks, but is now being used more often to produce electricity. Onshore and offshore windfarms are becoming increasingly prevalent, but wind power can also be used on a much smaller scale to produce electricity, even to provide a source of power for recharging mobile telephones.
These examples of renewable sources can be added to by others, such as geothermal , biomass and tidal power, which also all have their own benefits and applications. The future of clean energy looks bright, with recent years showing that more renewable energy capacity has been installed globally than new fossil fuel and nuclear capacity combined.
Renewable sources now make up over one-third of globally installed power capacity. As an example of this growth, Wednesday 10 June marked two months of the UK being powered purely by renewable energy for the first time ever.
As the world population continues to grow, there is an ever-increasing demand for energy and renewable sources are the answer to providing sustainable energy solutions, while also protecting the planet from climate change.
The take-up of clean energy is not just happening on a national level as cities and states are also crating policies to increase renewable energy use.
Of course, due to fossil fuels being a finite resource, it makes sense that the future is renewable and so it is expected that renewable sources will continue to increase in number, driving down the cost too.
Humans have been using fossil fuels for over years and, as their use increased, so did the release of the greenhouse gases that are produced when these fuels are burned. Generating renewable energy on—site using a system or device at the location where the power is used e. Purchasing renewable energy through renewable energy certificates RECs — also known as green tags, green energy certificates, or tradable renewable certificates — that represent the technology and environmental attributes of electricity generated from renewable resources.
Price competitiveness is the most obvious barrier to renewable energy installations. In many cases, barriers to expanding renewable energy are regulatory and therefore within state control.
Some examples include:. Unfavorable utility rate structures have been a perennial barrier to increased deployment of renewable energy technologies. Unless carefully monitored to encourage the development of distributed generation , rate structures can increase the cost of renewables e.
The absence of standard interconnection rules, or uniform procedures and technical requirements for connecting renewable energy systems to the electric utility's grid, can make it difficult, if not impossible, for renewable systems to connect to the electric utility's grid.
Large—scale renewable energy technologies are subject to all the necessary environmental permits of major industrial facilities. Renewable energy generation using new technologies can face permitting hurdles until permitting officials are familiar with the environmental effects of the generation processes.
Many renewable resources are located in remote areas that lack ready or cost—effective access to transmission. States that have not established clear utility regulations that enable investments in transmission to be reimbursable i. The number of renewable energy installations across states varies widely, reflecting individual state or regional priorities, and not always due to resource or technical potential.
For example, the top eight states ranked by the capacity of their installed solar power include states in the southwest and northeast CA, NJ, AZ, MA, NY, NV, TX, PA represent States have adopted a number of policies to support greater investment in and adoption of renewable energy technologies.
Renewable Portfolio Standards RPS require electric utilities and other retail electric providers to provide a specified percentage or amount of customer electricity with eligible renewable resources.
EPA has held multiple State Webinars on RPS. Policy details are available from EPA's Energy and Environment Guide to Action Chapter 5: Renewable Portfolio Standards. Public Benefits Funds for Renewable Energy are a pool of resources used by states to invest in clean energy supply projects.
Funds are typically created by levying a small charge on customers' electricity rates i. Output—Based Environmental Regulations establish emissions limits per unit of productive energy output of a process i.
Policy details are available from EPA's Energy and Environment Guide to Action Chapter 6: Policy Considerations for Combined Heat and Power: Policy Considerations for Combined Heat and Power.
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.
