The US can halve its emissions by 2030 – if they want to | MarketingwithAnoy

That said, he adds, it’s not a permanent solution. A future grid running quite whether renewable energy needs to be more flexible, as operators will not be able to burn fossil fuels to fill temporary gaps between energy demand and production. (At night during a heat wave, for example, people could run many air conditioners, but there would be no sun to power them.) This means that the infrastructure must be rebuilt to enable it to transport renewable energy over long distances. . “In the long run, however, there is just no alternative: we need to upgrade the transmission,” he says.

Electric cars can also prove to be valuable assets in balancing the power supply and demand by forming a distributed network of car batteries, which – together with home solar panels – network operators can make use of when needed. “If, for example, we could use the batteries from electric vehicles or batteries in the home, or if we could operate the roof [photovoltaics] of a set of customers and get them to coordinate to provide a specific service to support our transmission network, which would definitely help in trying to cope with intermittence, ”says Patricia Hidalgo-Gonzalez, Director of Renewable Energy and Advanced Mathematics Laboratory at UC San Diego and was not involved in the new paper. “It could relieve the stress in the grid very dramatically as we have more and more renewable energy.”

The studies agreed on two additional points: the economic and health benefits of decarbonization. Every step in the life cycle of fossil fuels, from extraction to processing to combustion, is terrible for the human body. “There are massive non-economic benefits,” Abhyankar says of the transition to clean energy. “What we found is that this transition can also avoid over 200,000 premature deaths and over $ 800 billion to a trillion dollars of other health [costs]”For example, as more cars become electric, air quality will improve, reducing the number of people affected by respiratory diseases.

The last point of agreement among the studies that Abhyankar and his colleagues have reviewed is that it is not the expense that will hold back the proliferation of renewable energy, batteries and electric cars. “The key point is: the cost will not be very high,” says Abhyankar. “In fact, some studies found that it could result in significant consumer savings.” For example, while putting solar panels on a home can be an expensive upgrade – especially without a significant tax deduction – it will save the homeowner money in the long run.

Instead, the stumbling block is the policies needed to implement them on a broader scale. Although Democrats currently control Congress and the White House, they have struggled to pass substantial climate legislation. The Build Back Better program would have boosted the production of renewable technology in the United States, including other climate benefitsand West Virginia Senator Joe Manchin torpedoed it. “It certainly comes as no surprise that we are nowhere near achieving our goal of reducing greenhouse gas emissions by about half by 2030,” said environmental economist Mark Paul of the New College of Florida. “I think everyone across the climate and political community is well aware that we are definitely going to blow past these goals, unless we have a significant effort in Washington. “

And everywhere, For that matter. For example, states could order more of their energy production to come from renewable energy, while U.S. authorities could provide greater tax rebates for people to buy electric cars, and cities could invest in charging stations for them, especially in neighborhoods with lower incomes.

Another bottleneck, Paul says, is the lack of skilled labor to implement and maintain solar and wind systems and energy-saving home technologies such as heat pumps. Public investment in business schools could help strengthen this workforce. “This actually provides a pretty deep economic opportunity to revitalize the American working class that has struggled,” Paul says. “We just need policy to steer the ship in the right direction and ensure that this transition happens as quickly as possible.”
