This is not one of the super fact posts. It is just a post related to an interest of mine that is informational. I volunteer for an organization called Citizens Climate Lobby, or CCL. CCL is a bipartisan organization that works with both Democrats and Republicans to create the political will for climate solutions. During the month of August CCL is promoting what is called electrification. Clean energy is taking the world with storm, but energy / electric power is not the only source of carbon emissions / greenhouse gases.
Take for example, transportation. Most cars still use gasoline and to move towards a fossil fuel free future we must move towards using transportation that uses less fossil fuels such as EV cars. We need to electrify transportation. Another aspect of electrification is replacing gas stoves with induction stoves, installing solar panels, as well as lowering the energy use of your house.
EV Cars
At least here in Texas it is quite common to believe that EV cars do not reduce emissions. After all EV cars use electricity from the dirty grid, right? Often this is said to environmentalists and people who care about fossil fuels emissions as if they don’t understand that the electricity for EV cars typically comes from the dirty grid. However, they do know that. In fact, they know a little bit more. EV cars are much more efficient than Internal Combustion Engine cars , or ICE, and therefore the emissions caused by EVs via the electrical grid, even a coal powered grid, is significantly less per mile. In fact, replacing gasoline-powered cars with EVs saves energy, regardless of the energy source used to recharge the EVs. For an ICE 16-25% of the original energy goes to the wheels whereas for an EV 87-91% of the original energy goes to the wheels.
On the other hand, it takes more energy to manufacture an EV battery for an EV car than it does to produce a combustion engine. So, the production of an electric vehicle does emit more carbon than a petrol car. However, the lower emissions resulting from driving an EV means that an electric car quickly pays back its debt, so to speak. It is typically paid back within two years.
According to Hannah Richie at Our World in Data the statistics show that switching from an average ICE to an equally sized EV will save 1.2 tons of carbon emissions per person and year. That is a lot considering that the average carbon footprint per year is 4 tons worldwide and 14.4 tons per year for an American. Hannah Richie at Our World in Data also states that other environmental damages related to EVs such as mining for minerals are less than mining and extraction for fossil fuel cars, and she claims that the price of lithium-ion batteries has fallen by 98% over the last three decades.
EVs are becoming increasingly common. According to Our World in Data in 2022, 88% of all cars sold in Norway were EVs and 54% of all cars in Sweden were EVs. The United States is lagging a bit at 7.5% but there is a tax credit $7,000.00 for new EVs and a $4,000.00 tax credit for buying used EVs. I should add that we have not yet bought an EV because after I took early retirement, I did not need a car. We just share my wife’s hybrid, which we hardly ever drive.
Induction Stoves
We bought an electric stove, an induction stove, a couple of years ago when our previous stove stopped working. They come with an $840.00 rebate. I’ve read that professional chefs prefer gas stoves. However, our induction stove provides everything we need for our cooking needs and my beer brewing needs and it is easier to clean. If you are a professional chef you may want to be able switch the high heat on and off quicker, but we are not professional chefs even though the food we cook is delicious.
Another downside of an induction stove is that if the power goes out you can’t cook, but that has not been a problem for us. Considering that we get our electricity from a power company, Green Mountain Energy, that utilizes renewable energy, wind and solar, you can claim that our stove is 100% fossil fuel free.
Heat Pumps
Air source heat pumps, which are the most common type of heat pumps, are a great, energy efficient choice for heating your home and water and as well as being low maintenance, they can help to cut your heating costs and lower your carbon footprint. An air source heat pump absorbs heat from the air outside a building and releases it inside. It uses the same vapor-compression refrigeration process and much the same equipment as an air conditioner, but in the opposite direction.
Air-to-air heat pumps provide hot or cold air directly to rooms. Heat pumps are the main way to phase furnaces but are also typically more efficient than other types of heaters and air conditioners and thus they reduce greenhouse gas emissions. There is an up to $8,000.00 upfront discount for heat pumps and a 30% tax credit up to $2,000.00. I should say we do not have a heat pump.
Rooftop solar
Another great thing that we have been thinking about but do not have yet is rooftop solar. Rooftop solar power system, or rooftop photo voltaic systems, consist of electricity-generating solar panels mounted on the rooftop of a residential or commercial building or structure. Residential rooftop solar power systems typically feature a capacity of about 5–20 kilowatts.
The average American household uses 1.2 kilowatts on average. Most rooftop solar systems are connected to the grid and can feed the extra power into the grid for compensation. I should add this is not entirely without difficulty. There are also hybrid systems which include any combination of wind turbines, diesel generators, and batteries for electricity on demand. There is a 30% tax credit for rooftop solar.
Miscellaneous Energy Savings
Saving energy is not exactly the same thing as electrification but it is a related topic. If you electrify your home and also reduce your energy needs, you are reducing emissions.
A few years ago, we changed the insulation in our house to reduce our energy needs and our electric bill. It made a difference. We also did weatherstripping, installed three pane windows and high security doors, that were well-insulated and reduced heat-loss. We received significant tax credits for doing this. I don’t remember how much, but it was several thousand dollars. I can add that you get a $150 tax credit for a home energy audit.
