Switching from coal to natural gas has advantages in terms of sustainability. For a given unit of energy produced, the life-cycle greenhouse-gas emissions of natural gas are around 40 times the emissions of wind or nuclear energy but are much less than coal.

Burning natural gas produces around half the emissions of coal when used to generate electricity and around two-thirds the emissions of coal when used to produce heat. Switching from coal to natural gas reduces emissions in the short term and thus contributes to climate change mitigation.

However, in the long term it does not provide a path to net-zero emissions. Developing natural gas infrastructure risks carbon lock-in and stranded assets , where new fossil infrastructure either commits to decades of carbon emissions, or has to be written off before it makes a profit.

The greenhouse gas emissions of fossil fuel and biomass power plants can be significantly reduced through carbon capture and storage CCS. Nuclear power has been used since the s as a low-carbon source of baseload electricity.

Nuclear power's lifecycle greenhouse gas emissions—including the mining and processing of uranium —are similar to the emissions from renewable energy sources. Additionally, Nuclear power does not create local air pollution. There is controversy over whether nuclear power is sustainable, in part due to concerns around nuclear waste , nuclear weapon proliferation , and accidents.

Reducing the time and the cost of building new nuclear plants have been goals for decades but costs remain high and timescales long. Fast breeder reactors are capable of recycling nuclear waste and therefore can significantly reduce the amount of waste that requires geological disposal , but have not yet been deployed on a large-scale commercial basis.

Several countries are attempting to develop nuclear fusion reactors, which would generate small amounts of waste and no risk of explosions. The emissions reductions necessary to keep global warming below 2 °C will require a system-wide transformation of the way energy is produced, distributed, stored, and consumed.

For example, transitioning from oil to solar power as the energy source for cars requires the generation of solar electricity, modifications to the electrical grid to accommodate fluctuations in solar panel output or the introduction of variable battery chargers and higher overall demand, adoption of electric cars , and networks of electric vehicle charging facilities and repair shops.

Many climate change mitigation pathways envision three main aspects of a low-carbon energy system:. Some energy-intensive technologies and processes are difficult to electrify, including aviation, shipping, and steelmaking.

There are several options for reducing the emissions from these sectors: biofuels and synthetic carbon-neutral fuels can power many vehicles that are designed to burn fossil fuels, however biofuels cannot be sustainably produced in the quantities needed and synthetic fuels are currently very expensive.

Full decarbonisation of the global energy system is expected to take several decades and can mostly be achieved with existing technologies. To deliver reliable electricity from variable renewable energy sources such as wind and solar, electrical power systems require flexibility.

There are various ways to make the electricity system more flexible. In many places, wind and solar generation are complementary on a daily and a seasonal scale: there is more wind during the night and in winter when solar energy production is low. With grid energy storage , energy produced in excess can be released when needed.

Building overcapacity for wind and solar generation can help ensure that enough electricity is produced even during poor weather. In optimal weather, energy generation may have to be curtailed if excess electricity cannot be used or stored.

The final demand-supply mismatch may be covered by using dispatchable energy sources such as hydropower, bioenergy, or natural gas. Energy storage helps overcome barriers to intermittent renewable energy and is an important aspect of a sustainable energy system.

Compared to the rest of the energy system, emissions can be reduced much faster in the electricity sector. Fossil fuels, primarily coal, produce the rest of the electricity supply.

Climate change mitigation pathways envision extensive electrification—the use of electricity as a substitute for the direct burning of fossil fuels for heating buildings and for transport. One of the challenges in providing universal access to electricity is distributing power to rural areas.

Off-grid and mini-grid systems based on renewable energy, such as small solar PV installations that generate and store enough electricity for a village, are important solutions.

Infrastructure for generating and storing renewable electricity requires minerals and metals, such as cobalt and lithium for batteries and copper for solar panels. Hydrogen gas is widely discussed in the context of energy, as an energy carrier with potential to reduce greenhouse gas emissions.

These applications include heavy industry and long-distance transport. Hydrogen can be deployed as an energy source in fuel cells to produce electricity, or via combustion to generate heat.

Nearly all of the world's current supply of hydrogen is created from fossil fuels. Producing one tonne of hydrogen through this process emits 6. Electricity can be used to split water molecules, producing sustainable hydrogen provided the electricity was generated sustainably.

However, this electrolysis process is currently financially more expensive than creating hydrogen from methane without CCS and the efficiency of energy conversion is inherently low. Hydrogen fuel can produce the intense heat required for industrial production of steel, cement, glass, and chemicals, thus contributing to the decarbonisation of industry alongside other technologies, such as electric arc furnaces for steelmaking.

Disadvantages of hydrogen as an energy carrier include high costs of storage and distribution due to hydrogen's explosivity, its large volume compared to other fuels, and its tendency to make pipes brittle.

Public transport typically emits fewer greenhouse gases per passenger than personal vehicles, since trains and buses can carry many more passengers at once. The energy efficiency of cars has increased over time, [] but shifting to electric vehicles is an important further step towards decarbonising transport and reducing air pollution.

Long-distance freight transport and aviation are difficult sectors to electrify with current technologies, mostly because of the weight of batteries needed for long-distance travel, battery recharging times, and limited battery lifespans.

Over one-third of energy use is in buildings and their construction. A highly efficient way to heat buildings is through district heating , in which heat is generated in a centralised location and then distributed to multiple buildings through insulated pipes. Traditionally, most district heating systems have used fossil fuels, but modern and cold district heating systems are designed to use high shares of renewable energy.

Cooling of buildings can be made more efficient through passive building design , planning that minimises the urban heat island effect, and district cooling systems that cool multiple buildings with piped cold water.

In developing countries where populations suffer from energy poverty , polluting fuels such as wood or animal dung are often used for cooking. Cooking with these fuels is generally unsustainable, because they release harmful smoke and because harvesting wood can lead to forest degradation.

cooking facilities that produce less indoor soot, typically use natural gas, liquefied petroleum gas both of which consume oxygen and produce carbon-dioxide or electricity as the energy source; biogas systems are a promising alternative in some contexts.

Over one-third of energy use is by industry. Most of that energy is deployed in thermal processes: generating heat, drying, and refrigeration.

The share of renewable energy in industry was The most energy-intensive activities in industry have the lowest shares of renewable energy, as they face limitations in generating heat at temperatures over °C °F. For some industrial processes, commercialisation of technologies that have not yet been built or operated at full scale will be needed to eliminate greenhouse gas emissions.

Experience has shown that the role of government is crucial in shortening the time needed to bring new technology to market and to diffuse it widely. International Energy Agency []. Well-designed government policies that promote energy system transformation can lower greenhouse gas emissions and improve air quality simultaneously, and in many cases can also increase energy security and lessen the financial burden of using energy.

Environmental regulations have been used since the s to promote more sustainable use of energy. Governments can require that new cars produce zero emissions, or new buildings are heated by electricity instead of gas. Governments can accelerate energy system transformation by leading the development of infrastructure such as long-distance electrical transmission lines, smart grids, and hydrogen pipelines.

Carbon pricing such as a tax on CO 2 emissions gives industries and consumers an incentive to reduce emissions while letting them choose how to do so.

For example, they can shift to low-emission energy sources, improve energy efficiency, or reduce their use of energy-intensive products and services. The scale and pace of policy reforms that have been initiated as of are far less than needed to fulfil the climate goals of the Paris Agreement.

Countries may support renewables to create jobs. Six million jobs would be lost, in sectors such as mining and fossil fuels. Raising enough money for innovation and investment is a prerequisite for the energy transition.

Most studies project that these costs, equivalent to 2. However, this goal has not been met and measurement of progress has been hampered by unclear accounting rules. Fossil fuel funding and subsidies are a significant barrier to the energy transition.

Options to switch to green power are steadily growing, so no matter where you live, there is an opportunity for you to make an energy choice that counts and supports a clean energy future.

However, to make sure that it is actually green power, EPA recommends that you choose third-party certified green power. See below for a list of options and where they are available. Homes and businesses nationwide are increasingly signing up to get their electricity from renewable resources.

In fact, choosing energy from renewable resources is one of the best ways to prepare for a clean energy future. Reduce your electricity usage as much as you can and buy clean energy for the rest.

You can purchase through a green power program offered by your local electricity provider or you can buy renewable energy certificates from online sellers.

Your purchases increase the demand for renewables, so more will be built. You are here Home Energy Efficient Products Green Power Options. Green Power Options One way you can do your part to reduce your carbon footprint is by switching to green power. Utility Green Power Products Green Pricing — Many households have the option to simply opt for green power for their electricity.

Utility green power products — often referred to as green pricing — are offered directly from your utility supplier so you can get information on these options by contacting your utility. You can also click here to access third-party certified green power products by state.

Competitive Green Power Products — Some customers may live in what are referred to as deregulated electricity markets. With clean energy technologies, the cost of power shouldn't swing around as the cost of fuel rises and falls. The U. already produces more energy than it consumes, but the cost of natural gas and other fossil fuels is still sensitive to worldwide demand.

Once you've built a clean-energy installation, the cost to run it over time is extremely low and isn't sensitive to changes in the costs of commodities. Renewables are considered "intermittent", meaning they aren't capable of producing energy at all times.

Additionally, there can be other unpredictable weather events that disrupt clean energy technologies. Geothermal energy is immune from this challenge, however. While there are storage technologies available, they can be expensive, especially for large-scale renewable energy plants.

The United States has a diverse geography with varying climates, topographies, vegetation, and more. This creates a beautiful variety of landscapes but also means that there are some areas that are more or less suitable for renewable technologies. Wind power and hydropower contributed over 16 percent combined, solar generated 3.

Geothermal produced less than half a percent of U. electrical generation. In the first five months of , solar and wind actually generated more power than coal for the first time. That followed similar feats in and when solar, wind, and hydropower combined all beat coal generation. Policy tools are essential to increasing the use of renewable energy sources for electricity generation, heating, cooling, and more.

Policies at the federal and state level promote renewables and help offset costs for customers of all sizes, from residential to utility-scale projects. The Database of State Incentives for Renewables and Efficiency, or DSIRE is the best place to browse current renewable energy policies at the federal and state level.

At the federal level, there are a few important policies to be aware of that prop up renewable energy adoption and development. The federal renewable energy Investment Tax Credit ITC can be applied to residential and commercial solar energy system installations and currently amounts to 30 percent of the total cost of installation.

The federal Production Tax Credit PTC is a primary incentive for large-scale renewable energy procurement. Currently, 38 states and Washington D. have renewable portfolio standards in place. Some state RPS guidelines even include specific requirements for individual renewable sources, such as solar carve-outs.

Other state-level policy tools to help bolster the adoption of renewable energy include net metering , RECs , and feed-in tariffs , all of which provide financial incentives for renewable energy investment.

Besides being environmentally friendly, many economic benefits come with renewable energy sources.
