ELECTRIFICATION EXPLAINED
What is electrification?
Electrification is the process of substituting fossil fuel-intensive processes with electrically-powered ones. Here are some examples:
-
Power plants that use coal, oil and natural gas as fuel can be augmented or replaced with a mix of solar, wind, hydropower and battery assets.
Diesel generators can be replaced with a combination of battery & solar installations.
It is not possible to replace every fossil-fueled power generator with renewables due to economics and/or geographical constraints.
-
Sources of carbon emissions in the commercial & residential sectors include: Space heating (boilers, furnaces, etc.), gas cookstoves, water heaters and clothes dryers. These can be replaced with electrical equivalents such as heat pumps, electrical boilers, electrical or induction stoves, heat pump water heaters and heat pump dryers.
-
Electric vehicles are a well-established alternative to gas-powered vehicles, though not in all vehicle classes yet. Rail & marine electrification is a growing trend while aviation remains a challenging mode of transportation to electrify.
-
Cement, petroleum, steel and steel production are carbon intensive processes. Electrification of these critical processes are in the early stages but show promise for the future
-
Irrigation represents 15% of the carbon emitted in the agricultural sector. Electrifying diesel irrigation pumps could reduce irrigation emissions by 90%
Another study found that electrifying far operations, including vehicles and irrigation would reduce the total carbon emissions of food by 20%
Agricultural electrification still needs more innovation to achieve these esimates.
What are the benefits of electrification?
There are several benefits to electrifying our modern world:
-
According to the International Renewable Energy Agency, a fully deployed electrification strategy could reduce carbon emissions by 70% relative to 2019 emissions
-
The air pollution from fossil-fuel processes is significant and affects populations differently by region. A 2022 study published in Nature Communications indicated that reductions in particulate from 30 to 80% are possible depending on different electrification scenarios. This leads to reduced health care costs and increased quality of life.
Switching from combustion to renewables would reduce noise pollution in many regions as well. Most gains would come from reduced vehicle and industrial process noise.
-
The operating and maintenance costs of many electrically-powered processes are less than those of fossil-fueled ones. Solar power, electric vehicles, heat pumps and stoves are just a few examples.
-
With more onsite generation and storage, facilities can increase their resilience to outages in centralized power generation plants.
-
There are several economic benefits of an electrifying economy:
Economic Growth: Electrification can stimulate economic growth by improving productivity and efficiency in industries. Reliable electricity supply reduces downtime and enhances production capabilities.
Job Creation: Transitioning to electric infrastructure, especially renewable energy projects, can create jobs in manufacturing, installation, maintenance, and related services.
Energy Security: Reducing dependence on imported fossil fuels enhances energy security and can improve trade balances. It also shields economies from volatile global oil prices.
Innovation and Investment: Electrification drives technological innovation and attracts investments in new technologies and infrastructure, fostering a more dynamic and competitive economy.
Industrial Competitiveness: Countries and regions that adopt electrification early can gain a competitive edge in emerging industries, such as electric vehicles and smart grids, positioning themselves as leaders in the global market.
