Where possible, all infrastructure projects should be evaluated for their potential to support biodiversity recovery and incorporate natural infrastructure.

Impacts differ. In some agricultural landscapes, for example, wind farms can be located with relatively little impact. Areas that supply critical habitat for migratory birds would likely be poor candidates for a wind farm location.

Where possible, existing linear infrastructure, such as railway rights-of-way or highway corridors, should be considered for transmission lines to avoid additional habitat fragmentation.

The electricity system of the future will operate differently than the one we have today. Sharing electricity between provinces will also cost less as the grid expands than having provinces rely on their own, separate systems. All provinces, regardless of their current electricity systems, can realize real benefits to a more connected electricity grid.

Indigenous world views and knowledge need to be incorporated and respected within broader societal and economic value systems;. Meaningful, rights-based and consent-based consultation must become common practice for all clean energy projects;.

Existing Indigenous leadership needs to be honoured and advanced through support for capacity, ownership opportunities and jobs;. Indigenous leaders require a seat at decision-making tables, as decarbonizing electricity must also mean decolonizing power structures;.

Solving systemic infrastructure gaps for Indigenous communities through focused just transition measures must be prioritized as part of the clean energy transition; and. Economic reconciliation must be central to the clean energy transition by removing barriers to accessing financial capital, ownership and other project benefits.

All models have limitations and are not predictive by design. The modelling simplifies the real world, seeking only least-cost solutions to building out future generation, storage and transmission capacity to meet future energy demand within scenario settings and constraints.

Other factors will need to influence the grid of the future, including local preference for what renewable generation is built where, how provincial grid interties are strengthened and how electricity markets are structured.

These pathways need to be technically feasible and socially acceptable. Off-grid and remote electricity systems and territorial grids or non-integrated electricity systems are beyond the scope of this report.

Technologies such as offshore wind, geothermal generation, distributed energy resources, demand response, green hydrogen and hybrid projects e. Government has already made concessions to industry, including delaying the release of the Clean Fuel Regulations from to , and removing heating oil and gaseous and solid fuels from the agreement, leaving only gasoline and diesel covered.

Industry has had three years to prepare for these regulations. The Clean Fuel Regulations are a polluter-pay policy focused on refinery operations. They include flexibility to incentivize innovation. It is irresponsible for industry to pass on increased costs to consumers when their own inaction is causing problems.

Delaying the implementation of these regulations is not a viable option. Climate regulations like Clean Fuel Regulations are needed to drive down emissions and lessen the impacts of severe and more frequent fires, floods and droughts.

Climate inaction or delay costs us more in the long run. They are based on a worst — case scenario by the PBO that ignores the benefits, overstates the costs on household budgets and neglects the costs of using alternative mechanisms to reduce emissions.

There is much economic potential in climate action: the regulations position Canada to compete in the global decarbonizing economy, attracting new investments and creating tangible benefits.

Forty-six organizations delivered this letter to the Government of Canada to send a clear message that robust clean electricity regulations are needed to avoid dead-end pathways and achieve a net-zero electricity system by throughout Canada.

Reliable, affordable, clean electricity in Canada by is entirely possible. This is the first Canadian modelling study to explore how to get there largely through wind and solar and without relying on expensive and sometimes unproven and environmentally dangerous technologies.

Canada has a goal of per cent zero-emissions electricity by The benefits of adding wind and solar to power that electricity go deeper than fighting climate change; they include more affordable energy bills, healthier homes and more good quality jobs. Interim measures with signals to utilities are needed between now and The cost-of-living crisis and the climate crisis share the same root cause: expensive oil and gas.

Transitioning to clean electricity protects not just the planet but also pocketbooks. The lowest electricity costs are found in provinces with the cleanest grids. What can we help you find? Sorry, but your search returned no results. Try searching with different keywords.

Having supplied just 2. Green energy is important for the environment as it replaces the negative effects of fossil fuels with more environmentally-friendly alternatives. Derived from natural resources, green energy is also often renewable and clean, meaning that they emit no or few greenhouse gases and are often readily available.

Even when the full life cycle of a green energy source is taken into consideration, they release far less greenhouse gases than fossil fuels, as well as few or low levels of air pollutants.

This is not just good for the planet but is also better for the health of people and animals that have to breathe the air. Green energy can also lead to stable energy prices as these sources are often produced locally and are not as affected by geopolitical crisis, price spikes or supply chain disruptions.

The economic benefits also include job creation in building the facilities that often serve the communities where the workers are employed. Renewable energy saw the creation of 11 million jobs worldwide in , with this number set to grow as we strive to meet targets such as net zero.

Due to the local nature of energy production through sources like solar and wind power, the energy infrastructure is more flexible and less dependent on centralised sources that can lead to disruption as well as being less resilient to weather related climate change.

Green energy also represents a low cost solution for the energy needs of many parts of the world. This will only improve as costs continue to fall, further increasing the accessibility of green energy, especially in the developing world.

There are plenty of examples of green energy in use today, from energy production through to thermal heating for buildings, off-highway and transport. Many industries are investigating green solutions and here are a few examples:.

These include solar water heaters, biomass fuelled boilers and direct heat from geothermal, as well as cooling systems powered by renewable sources. Renewable heat for industrial processes can be run using biomass or renewable electricity.

Hydrogen is now a large provider of renewable energy for the cement, iron, steel and chemical industries. Sustainable biofuels and renewable electricity are growing in use for transportation across multiple industry sectors.

Automotive is an obvious example as electrification advances to replace fossil fuels, but aerospace and construction are other areas that are actively investigating electrification.

Green energy has the capacity to replace fossil fuels in the future, however it may require varied production from different means to achieve this. Geothermal, for example, is particularly effective in places where this resource is easy to tap into, while wind energy or solar power may be better suited to other geographic locations.

However, by bringing together multiple green energy sources to meet our needs, and with the advancements that are being made with regards to production and development of these resources, there is every reason to believe that fossil fuels could be phased out. We are still some years away from this happening, but the fact remains that this is necessary to reduce climate change, improve the environment and move to a more sustainable future.

Understanding the economic viability of green energy requires a comparison with fossil fuels. The fact is that as easily-reached fossil resources begin to run out, the cost of this type of energy will only increase with scarcity.

At the same time as fossil fuels become more expensive, the cost of greener energy sources is falling. Other factors also work in favour of green energy, such as the ability to produce relatively inexpensive localised energy solutions, such as solar farms.

The interest, investment and development of green energy solutions is bringing costs down as we continue to build up our knowledge and are able to build on past breakthroughs.

Efficiency in green energy is slightly dependent on location as, if you have the right conditions, such as frequent and strong sunlight, it is easy to create a fast and efficient energy solution.

However, to truly compare different energy types it is necessary to analyse the full life cycle of an energy source. This includes assessing the energy used to create the green energy resource, working out how much energy can be translated into electricity and any environmental clearing that was required to create the energy solution.

Currently, wind farms are seen as the most efficient source of green energy as it requires less refining and processing than the production of, for example, solar panels. Advances in composites technology and testing has helped improve the life-span and therefore the LEC of wind turbines.

However, the same can be said of solar panels, which are also seeing a great deal of development. Green energy solutions also have the benefit of not needing much additional energy expenditure after they have been built, since they tend to use a readily renewable source of power, such as the wind.

Renewable energy sources are currently ranked as follows in efficiency although this may change as developments continue :. Green energy provides real benefits for the environment since the power comes from natural resources such as sunlight, wind and water.

Constantly replenished, these energy sources are the direct opposite of the unsustainable, carbon emitting fossil fuels that have powered us for over a century. Creating energy with a zero carbon footprint is a great stride to a more environmentally friendly future. If we can use it to meet our power, industrial and transportation needs, we will be able to greatly reduce our impact on the environment.

As we touched upon earlier, there is a difference between green, clean and renewable energy. This is slightly confused by people often using these terms interchangeably, but while a resource can be all of these things at once, it may also be, for example, renewable but not green or clean such as with some forms of biomass energy.

Green energy is that which comes from natural sources, such as the sun. Clean energy are those types which do not release pollutants into the air, and renewable energy comes from sources that are constantly being replenished, such as hydropower, wind power or solar energy. Renewable energy is often seen as being the same, but there is still some debate around this.

However, a source such as wind power is renewable, green and clean — since it comes from an environmentally-friendly, self-replenishing and non-polluting source. Readily replenished, these energy sources are not just good for the environment, but are also leading to job creation and look set to become economically viable as developments continue.

The fact is that fossil fuels need to become a thing of the past as they do not provide a sustainable solution to our energy needs. By developing a variety of green energy solutions we can create a totally sustainable future for our energy provision, without damaging the world we all live on.

You may not realize that renewable energies can cause pollution. For example, biogas and biodiesel are renewable sources of energy because, among other things, they come from natural, inexhaustible sources.

However, unlike most renewable energies, they pollute the atmosphere on combustion, emitting greenhouse gases. Clean energies do not pollute and, therefore, it is fair to say that most renewable sources of energy are also clean and vice versa.

Most clean energy is also renewable and therefore, in addition to nuclear energy - which we will address later on - the following are currently the most common:. It is a clean, renewable, local, inexhaustible source of energy obtained by transforming the kinetic energy from the wind into electricity.

There are two types, according to where the wind turbines are installed:. Onshore wind energy : it uses currents of air produced on land.

Offshore wind energy : It uses the wind that blows on the high seas , where they reach higher speeds and are more constant. How does offshore wind energy work? Video voice transcription Spanish version External link, opens in new window. Photovoltaic solar energy is clean, renewable, local and inexhaustible source of power that converts sunlight into electricity using the photovoltaic effect.

Hydroelectric energy is a clean, renewable, emissions-free, local source of power that uses the force of water falling from a height or running down a slope to produce electricity.

This type of power generation can be divided into hydroelectric pumping stations , the most efficient, large-scale energy storage method in existence. Energy storage, in addition to integrating renewables, brings efficiency savings to the electrical grid. Green hydrogen is based on generating hydrogen, a universal, light and highly reactive fuel , using a chemical process known as electrolysis.

This method uses an electric current to separate the hydrogen from the oxygen in water, so if this electricity is obtained from renewable sources, we will produce energy without emitting carbon dioxide into the atmosphere. It is a source of clean, renewable energy that produces electricity by burning natural organic material or organic waste produced by human activity.

It is a type of clean, renewable and inexhaustible energy that harnesses the heat that radiates from the center of the Earth using power plants located on deposits.

These may be hot water deposits, in which case the heat comes from layers of hot water flowing beneath the surface, or dry, which uses heat from rocks.

It is a source of clean, renewable, local and inexhaustible generation that converts the power of waves into electricity. Other types of renewable energy include solar thermal energy , which uses the heat of the sun, wave energy , which converts the energy from waves, and ocean thermal energy conversion, which uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawater.

As well as these, more and more hybrid energy projects are emerging that combine different renewable generation sources to ensure a more stable, efficient supply. Despite what many people think, nuclear energy is clean throughout its generation, as well as being almost inexhaustible using current uranium reserves, which will be able to continue producing the same quantity of energy for thousands of years.

In fact, most nuclear reactors only emit water vapour into the atmosphere. Neither CO2, nor methane, nor any other type of polluting gas that aggravates climate change is part of the equation.

What's more, we must not forget the enormous amount of energy a single power station can generate because of the massive power stored in nuclear energy.

This energy is obtained in two ways: nuclear fusion and fission. In the first of these, energy is released when the nuclei of atoms combine or fuse together to create a larger nucleus. In the second, the nuclei separate to form smaller ones and, in turn, release energy. As you can see, there are numerous types of renewable energy, but what do they all have in common?

They are environmentally friendly : no clean energies generate greenhouse gases or other polluting emissions into the atmosphere.

They are unlimited: we obtain them from inexhaustible or rapidly regenerating natural resources , so they can be used indefinitely and without limit.

They promote energy independence : because they use natural resources found all over the planet, so that countries and regions are able to develop their own technologies rather than depending on electricity produced abroad.

They create jobs and boost the local economy : most renewable facilities are labour-intensive to build, maintain and operate, which creates jobs and stimulates the national economy. The United Nations predicts that the world population could reach 8.

Two-thirds of them live in cities and living standards are improving as emerging countries join the global middle class. All this means a higher worldwide demand for energy , which could increase according to the most recent report issued by the U.

Energy Information Administration EIA. Fossil fuels cannot satisfy this demand. Firstly, because it is estimated that oil reserves will be exhausted within 40 to 50 years and natural gas, within 60 to 80 years.

Secondly, because fossil fuel combustion releases greenhouse gas emissions into the atmosphere, causing global warming and climate change , the main menaces to humanity in the 21st century.

In such a scenario, it is crucial to opt for safer, more plentiful and less environmentally damaging sources of energy. Solar PV alone accounted for more than half of new renewable energy installations with a record GW, followed by 93 GW of wind power overall, 21 of which are offshore wind installations.

At the Iberdrola group, we are a world leader in renewable energies , in addition to being leaders in installed renewable capacity.

These energies are the fundamental pillar on which our clean, reliable and intelligent business model is built. Thanks to our investment plan - extended to - we aim to double this renewable capacity to 60 GW in , while reaching 95 GW in One of the main keys to the group's future growth is offshore wind , which is the second most important technology thanks to the strong growth experienced in the last year.

Our goal is to consolidate our position as a global benchmark in offshore wind, and thanks to the expansion of our offshore wind portfolio, we are in an unbeatable position to participate in auctions and tenders that arise, both for existing projects and for new opportunities.

Hydropower is the clean, renewable source with the largest installed capacity worldwide. Moreover, efficient, reliable renewable technologies can create a system less prone to market shocks and improve resilience and energy security by diversifying power supply options.
