What You'll Learn
China is the world's largest producer and consumer of electricity
China's renewable energy sector is growing rapidly, with renewables now accounting for half of its installed capacity. China is on track to have at least 2461 GW of renewable electricity capacity installed by 2030, with solar capacity nearly tripling. The country has also developed a near monopoly on supply chains for clean energy technologies, including the mining and processing of rare earths and strategic minerals. BYD, a Chinese company, has become the world's biggest EV manufacturer, challenging established vehicle brands in electric transportation.
Despite the growth in renewables, China still generates about 70% of its electricity from fossil fuels, mainly coal. Over half of the world's coal-fired power is generated in China, and coal-fired power stations generated 57% of electricity in 2020. China is the largest producer and consumer of coal globally and the largest user of coal-derived electricity. Coal generation reached a record high in 2024, and the country is the world's largest emitter of coal mine methane (CMM). Emissions from coal mining are rising, and there has been a surge in permits for new coal-fired power plants.
To better manage supply and demand, China plans to create a unified national power market by 2030 by merging its six regional grids. This could enhance China's position as a global leader in renewable energy capacity and improve the utilisation of its clean energy production.

Natural gas was the top source of US electricity in 2023
In 2023, the United States generated about 4.18 trillion kilowatthours (kWh) of electricity at utility-scale electricity generation facilities. Fossil fuels, including coal, natural gas, petroleum, and other gases, accounted for about 60% of this electricity generation. Among these fossil fuels, natural gas stood out as the top source of electricity in the country. It had a generation share of 43%, far surpassing that of coal, which has been on a downward trend over the past decade.
The shift towards natural gas as the predominant fuel source for electricity generation reflects a broader transition in the US energy landscape. While coal has traditionally been a major energy source, its use has been decreasing. In contrast, natural gas and renewable energy sources have gained traction. This shift can be attributed to various factors, including the abundance of natural gas resources in the US, advancements in extraction and production technologies, and the perception of natural gas as a cleaner alternative to coal.
Natural gas is a fossil fuel that primarily consists of methane. It is formed from the decomposition of organic matter over millions of years. The production and use of natural gas have significant environmental implications. While it burns cleaner than other fossil fuels, releasing fewer harmful emissions, the extraction and distribution processes can contribute to greenhouse gas emissions, particularly when natural gas leaks into the atmosphere.
The use of natural gas for electricity generation offers certain advantages. It is highly efficient, providing a significant amount of energy output relative to the amount of fuel input. Natural gas power plants can also be quickly ramped up or down to meet changing electricity demands, making them valuable for balancing variable renewable energy sources like wind and solar power. Additionally, natural gas infrastructure is widely established, making it readily available for electricity generation.
While natural gas was the top source of US electricity in 2023, it is important to recognize the growing contribution of renewable energy sources. Renewable energy, including wind, solar, hydro, and geothermal power, accounted for about 21% of total US utility-scale electricity generation in 2023. This marks a significant increase from 1990 when renewable resources provided only about 12%. The expansion of renewable energy capacity and technological advancements are driving a cleaner and more sustainable energy future for the United States.

Ovens and stoves use a lot of electricity
Ovens and stoves are energy-intensive appliances that consume a lot of electricity. On average, electric stoves use 1,000 to 3,000 watts of electricity, while ovens use 2,000 to 5,000 watts. Using a stove and oven for a combined seven hours per week will use about 1,022 kilowatt-hours (kWh) of electricity per year, costing an average of $12.08 per month and about $145 per year.
The amount of electricity consumed depends on the wattage of the appliance and the length of time it is used. Higher wattage appliances will use more electricity, and the longer they are used, the higher the energy consumption. Ovens and stoves need to be connected to a 240-volt outlet and can pull anywhere from 20 to 60 amps.
There are ways to reduce electricity consumption when using ovens and stoves. For example, using a smaller appliance such as a toaster oven, microwave, or slow cooker can be more energy-efficient. Another tip is to avoid preheating the oven unless necessary, as preheating can be wasteful, especially when cooking small amounts of food. Turning off the burners a few minutes before the dish is ready and allowing residual heat to finish the job can also help reduce electricity usage.
Additionally, investing in energy-efficient appliances can significantly impact electricity consumption. For instance, a gas range is generally more energy-efficient than an electric stove. Self-cleaning ovens with better insulation can also improve energy efficiency by retaining heat. Convection ovens, which use a fan to circulate hot air, can reduce energy usage by up to 20%.
To further reduce electricity costs, installing solar panels is an effective option. Solar panels convert sunlight into electricity, and the more light there is, the more electricity is generated. This can help offset peak electricity usage and provide long-term savings.

HVAC systems use 46% of a US home's energy
In the US, HVAC systems use the highest amount of electricity in the residential sector, accounting for 46% of a US home's energy consumption. This is followed by lighting, which was previously the largest share of electricity use in the commercial sector, but its consumption has decreased due to the increasing use of high-efficiency lighting equipment.
HVAC systems include heating, ventilation, and air conditioning, with the latter two being responsible for the largest annual uses of electricity in the residential sector. The amount of electricity consumed by HVAC systems depends on the unit's efficiency, with a range of 28-63 kWh in a 24-hour period, resulting in about 850-1,950 kWh per month.
To reduce energy consumption and keep utility bills low, it is recommended to only use air conditioning when necessary, typically during the hottest parts of the day, and to regularly service the air conditioning and furnace. Additionally, using smaller appliances, such as toaster ovens, microwaves, or slow cookers, and opting to use the oven and stove during cooler hours of the day can help reduce the load on the HVAC system.
Installing home solar panels or transitioning to a solar power system can be a more permanent and effective way to save money on utility bills. Photovoltaic cells in solar panels convert sunlight into electricity, and the more light there is, the more electricity is created. This can help offset peak usage and provide savings stability.
