What Uses the Most Energy in Your Home?
Warren Buffett describes his first rules of investing as: “Rule #1: Never lose money. Rule #2: Don’t forget rule #1”.
But losing money doesn’t just happen in a stock portfolio – it’s also a common occurrence in other facets of life. That’s why Warren Buffett leads such a frugal lifestyle. He knows that every extra dollar spent on something he doesn’t need is wasted capital.
In practically every house in America, capital is being wasted on energy consumption. That’s because the average electricity spend per year is $1,368.36 per year, and 35% of the power used is actually wasted.
This is neither good for your bank account or the environment.
What Uses the Most Energy in Your Home?
Today’s infographic from Connect4Climate shows the breakdown in the energy use of a typical home.
It highlights the average cost per year of different appliances, while also showing what uses the most energy over the course of the year.
Modern comfort comes at a price, and keeping all those air conditioners, refrigerators, chargers, and water heaters going makes household energy the third-largest use of energy in the United States.
Here’s what uses the most energy in your home:
- Cooling and heating: 47% of energy use
- Water heater: 14% of energy use
- Washer and dryer: 13% of energy use
- Lighting: 12% of energy use
- Refrigerator: 4% of energy use
- Electric oven: 3-4% of energy use
- TV, DVD, cable box: 3% of energy use
- Dishwasher: 2% of energy use
- Computer: 1% of energy use
One of the easiest ways to reduce wasted energy and money? Shut off “vampire electronics”, or devices that suck power even when they are turned off. These include digital cable or satellite DVRs, laptop computers, printers, DVD players, central heating furnaces, routers and modems, phones, gaming consoles, televisions, and microwaves.
Warren Buffett would probably agree that a penny saved is a penny earned – and being more efficient with your energy use is good for your pocketbook and the environment.
Countries
Charted: The World’s Biggest Oil Producers
Just three countries—the U.S., Saudi Arabia and Russia—make up the lion’s share of global oil supply. Here are the biggest oil producers in 2022.

Charted: The World’s Biggest Oil Producers in 2022
In 2022 oil prices peaked at more than $100 per barrel, hitting an eight-year high, after a full year of turmoil in the energy markets in the wake of the Russian invasion of Ukraine.
Oil companies doubled their profits and the economies of the biggest oil producers in the world got a major boost.
But which countries are responsible for most of the world’s oil supply? Using data from the Statistical Review of World Energy by the Energy Institute, we’ve visualized and ranked the world’s biggest oil producers.
Ranked: Oil Production By Country, in 2022
The U.S. has been the world’s biggest oil producer since 2018 and continued its dominance in 2022 by producing close to 18 million barrels per day (B/D). This accounted for nearly one-fifth of the world’s oil supply.
Almost three-fourths of the country’s oil production is centered around five states: Texas, New Mexico, North Dakota, Alaska, and Colorado.
We rank the other major oil producers in the world below.

Behind America’s considerable lead in oil production, Saudi Arabia (ranked 2nd) produced 12 million B/D, accounting for about 13% of global supply.
Russia came in third with 11 million B/D in 2022. Together, these top three oil producing behemoths, along with Canada (4th) and Iraq (5th), make up more than half of the entire world’s oil supply.
Meanwhile, the top 10 oil producers, including those ranked 6th to 10th—China, UAE, Iran, Brazil, and Kuwait—are responsible for more than 70% of the world’s oil production.
Notably, all top 10 oil giants increased their production between 2021–2022, and as a result, global output rose 4.2% year-on-year.
Major Oil Producing Regions in 2022
The Middle East accounts for one-third of global oil production and North America makes up almost another one-third of production. The Commonwealth of Independent States—an organization of post-Soviet Union countries—is another major regional producer of oil, with a 15% share of world production.
Region | 2022 Production (Thousand B/D) | YoY Change | Share of World Supply |
---|---|---|---|
Middle East | 30,743 | +9.2% | 32.8% |
North America | 25,290 | +5.3% | 27.0% |
CIS | 14,006 | +0.9% | 14.9% |
Africa | 7,043 | -3.5% | 7.5% |
Asia Pacific | 7,273 | -1.4% | 7.8% |
South & Central America | 6,361 | 7.2% | 6.8% |
Europe | 3,131 | -8.6% | 3.3% |
What’s starkly apparent in the data however is Europe’s declining share of oil production, now at 3% of the world’s supply. In the last 20 years the EU’s oil output has dropped by more than 50% due to a variety of factors, including stricter environmental regulations and a shift to natural gas.
Another lens to look at regional production is through OPEC members, which control about 35% of the world’s oil output and about 70% of the world’s oil reserves.
When taking into account the group of 10 oil exporting countries OPEC has relationships with, known as OPEC+, the share of oil production increases to more than half of the world’s supply.
Oil’s Big Balancing Act
Since it’s the very lifeblood of the modern economy, the countries that control significant amounts of oil production also reap immense political and economic benefits. Entire regions have been catapulted into prosperity and wars have been fought over the control of the resource.
At the same time, the ongoing effort to pivot to renewable energy is pushing many major oil exporters to diversify their economies. A notable example is Saudi Arabia, whose sovereign wealth fund has invested in companies like Uber and WeWork.
However, the world still needs oil, as it supplies nearly one-third of global energy demand.
