U.S. Administration In order to achieve a net zero zero economy by 2050, household electrification will be one of the ways to reduce greenhouse gas emissions in the housing sector. But not all electricity is as easy as it seems.
The “develop everything” drive comes to the forefront and – in some cases – high maintenance costs for consumers, high costs for home construction contractors, and premature gas cooking and boiler and saddle elevators. Power bills.
In addition, all electric homes with electric chargers are expected to increase their demand for electricity, which some networks do not control and require billions of dollars in upgrades.
According to the Environmental Protection Agency (EPA), emissions from commercial and residential sectors in 2019 accounted for 13 percent of U.S. greenhouse gas emissions. Data. These emissions are primarily derived from fossil fuels, the use of certain greenhouse gases, and the handling of waste.
All electric homes have the potential to reduce these emissions, but switching from natural gas and oil to electric appliances and heat pumps will be more challenging for consumers and governments than it needs to be.
High electronics costs
The first and most obvious obstacle for all electric homes is price.
Proponents of a proposed gas pipeline in new homes would have called for greater power bills and grid overloads, as well as consumers’ right to choose their own homes. Many consumers, especially in colder climates, are aware that traveling all the electricity will increase their utility bills. Opponents of all electric buildings say that it can be a major obstacle for low-income families who do not use or cook any fossil fuel for their homes.
In colder cities like Denver and Minneapolis, the total construction costs for all electric homes are between $ 11,000 and $ 15,000. Study Prepared for the National Association of Home Builders (NAHB) earlier this year. In tropical climates such as Houston, total construction costs range from $ 3,988 to $ 11,196.

Overall, the study found that all electric homes are more expensive compared to gas stations. According to the NAHB, electric homes in colder climates have higher persistent utility costs.
With a high demand for electricity, improvements may be needed in the utility. Depending on local utility tariffs, these costs are high and need further assessment, ”the study said.
Vladimir Kochkin, director of codes and standards at NAHB, said: “It’s easy to write a paper and switch to A, but once you enter it, you realize it’s not that easy.” Houston ChronicleJames Osborne.
“Our members must eventually build these houses and sell them,” said Kokkin.
Most consumers do not sell all home appliances.
What NAHB Home Buyers Really Want, 2021 Edition Study Showed Consumers generally prefer electricity (51 percent) to gas (33 percent) for their air conditioning and refrigeration systems, while cooking (51 percent) to electricity (39 percent). Regardless of the region or system, the main factors contributing to the choice of respondents are financial savings and reliability, according to the study.
Cities Vs States
Although many cities are pushing to ban fossil fuels in new homes, consumer preferences are still divided, leading to natural gas in many parts of the United States.
Some U.S. cities are issuing regulations – or are trying to pass them Prohibition of natural gas connections In new homes, citing efforts to reduce climate change concerns and energy supply.
The search for so many American cities and towns to make all the newly built houses all electric has led to heavy fighting in dozens of states, many to Prohibition in advance Cities should not ban natural gas in new homes.
The battle is also between gas lobbyists and environmentalists, as many consumers — in support of their state’s clean energy goals — increase energy bills and increase the cost of building and maintaining a new electric home.
Grid reliability with high electrical demand
Electrification can also be a challenge for electric grid operators and the federal government, as high energy demand can disrupt distribution systems.
For example, the growth of heat pumps and EVs in New England will increase energy demand this decade, says the New England Independent System Operator (ISO-NE), which manages Connecticut, Maine Planning, the Power Market and Transmission Grid. , Massachusetts, New Hampshire, Rhode Island and Vermont. But high demand does not jeopardize the region’s grid, says ISO Adler, editor, climate and sustainability team at IHS Markit Wrote Earlier this year.
However, the combination of ISO-NE heat pumps and EVs will increase the maximum winter demand to 2,500 MW or more than the current maximum demand.
The addition of new pipelines in the region has been held to allow cases and charges, thus balancing the region’s energy system without additional natural gas pipeline capacity.
If the systems are not ready and better equipped to control solar and wind power, some areas in the United States may see the ultimate joke of all electric homes powered by fossil fuels such as natural gas.
