What You'll Learn
Energy efficiency at home
Fossil fuels are a major source of energy for households, with homes producing a significant amount of emissions. In Canada, households accounted for almost a quarter of the energy used in the country in 2019, with over 18% of the country's total GHG emissions. Similarly, in the US, burning fossil fuels accounted for 74% of greenhouse gas emissions in 2019.
To preserve fossil fuels and manage their consumption, individuals can take several measures to improve energy efficiency at home. Here are some ways to achieve this:
Electrification
Switching from fossil fuels to electricity for heating and cooking is a more efficient and environmentally friendly alternative. Electric heating and cooking appliances, such as induction stoves or cooktops, are more energy-efficient than traditional gas options. They produce heat almost instantly and do not release dangerous toxins or pollutants like CO2 and nitrogen dioxide, which are harmful to health and contribute to climate change.
Efficient Appliances
Opting for energy-efficient appliances can significantly reduce energy consumption. Look for appliances with high energy star ratings, as they consume less energy. For example, a heat pump water heater is up to 60% more efficient than a conventional electric water heater and is eligible for rebates.
Lighting
Switching to LED lights is an easy way to cut energy use by up to 80%. LED lights consume significantly less energy than traditional incandescent or fluorescent lights, resulting in lower energy bills and reduced environmental impact.
Home Improvements
Making simple changes around the house can improve energy efficiency. This includes adding insulation, installing energy-efficient windows, and using programmable thermostats to regulate heating and cooling. These measures help maintain a comfortable temperature in the home while reducing energy usage.
Renewable Energy Sources
Transitioning to renewable energy sources is a key strategy in preserving fossil fuels. Solar panels, wind turbines, hydropower, and bioenergy are all viable options for generating electricity or heating water without relying on fossil fuels. These sources are abundant, replenishable, and emit little to no greenhouse gases, making them a more sustainable choice.
By implementing these measures, individuals can significantly contribute to the preservation of fossil fuels, reduce their environmental impact, and lower their energy costs.

Fuel-efficient transport
Transportation is one of the largest consumers of fossil fuels, accounting for about 30% of total US energy consumption in 2023. This figure is likely to be similar or even higher in other countries. Therefore, improving fuel efficiency in transport is crucial for preserving and managing fossil fuels.
One way to improve fuel efficiency is to opt for fuel-efficient vehicles. This includes vehicles with better fuel economy, such as electric cars, which can lower fuel consumption. Electric vehicles require much less primary energy to run than traditional fossil fuel-powered cars, and they produce zero direct emissions. Hybrid vehicles are also a more fuel-efficient option, combining traditional fuel with electricity.
Another way to increase fuel efficiency in transport is to utilise public transit systems. Buses, trains, and other mass forms of transit reduce the number of single riders, thereby cutting down fuel consumption and emissions. In addition, shared mobility options such as carpooling, ridesharing, and car-sharing can also help reduce fuel consumption by decreasing the number of vehicles on the road.
Active transit methods such as walking or bicycling instead of driving for short trips can also significantly reduce fossil fuel consumption. Velomobiles (enclosed recumbent bicycles) are an excellent option for those wanting to cycle but seeking more protection from the elements. They have the highest energy efficiency of any known mode of personal transport due to their small frontal area and aerodynamic shape.
Finally, the use of renewable energy sources in transport can help preserve fossil fuels. Biofuels, for example, can be blended into gasoline, diesel fuel, and jet fuel. Natural gas is also used in some vehicles, and renewable energy sources such as solar, wind, hydropower, and bioenergy can be utilised to generate electricity, reducing dependence on fossil fuels.

Carbon capture and storage
CCS projects are storing over 50 million tons of CO2 annually, which is comparable to the emissions of a small country. Capture usually occurs at large stationary sources of CO2, such as power plants. Most carbon capture projects use a liquid to chemically remove the CO2 before it exits the smokestack, but new capture processes are being developed. For instance, pre-combustion carbon capture can be combined with an integrated gasification combined cycle (IGCC) power plant that burns H2 in a combustion turbine and uses the exhaust heat to power a steam turbine. Post-combustion carbon capture typically uses chemical solvents to separate carbon dioxide from the flue gas resulting from fossil fuel combustion. Oxyfuel carbon capture requires fossil fuel combustion in pure oxygen, resulting in exhaust gas that is carbon-dioxide-rich, facilitating capture.
Once captured, the CO2 gas is compressed into a liquid-like state and transported through pipelines to a storage site. At the storage site, the CO2 is pumped more than 2,500 feet down into geological formations such as depleted oil and gas reservoirs or formations with unusable, salty water. Geologists seek sites with porous rock that can absorb large quantities of CO2 and are covered by a "cap rock" layer with no nearby fault lines to prevent CO2 from escaping back to the surface.
While CCS is important for mitigating climate change, it is not the only solution. Diversifying energy sources away from fossil fuels and towards renewable sources is also crucial.
