If United States always make in the formation of the weather carbon air, should put the use of solar energy, most of which can be made from the roofs of homes and businesses. The sun provides only 3% of US electricity today, but the White House is saying that if California is forced to pass 40% in the coming years.
To get there, homeowners and businesses will need financial incentives to set up photovoltaic panels, while large-scale farms also need land and transmission systems to transfer energy from rural to urban areas. Last week, state officials in California demanded that builders install solar panels and batteries in the new commercial and luxury homes house. But new research they find a place with less money and less space can be left behind, mainly because the demands have not increased the power supply equally anywhere.
Even if the rooftops were free for everyone, the authors say, homeowners in these areas would not be able to use solar energy to run electrical appliances or drive an electric car without buying a special battery. This is because the power grid in these areas will not accept the additional electrical output generated by solar panels.
“There is not enough energy for everyone to have access to solar energy, even if the solar system were free,” says Anna Brockway, lead author of a study published this week in the newspaper. Natural Powers and a graduate student at the Energy and Resources Group at UC Berkeley. “We find that the shortcomings are particularly acute in the black and white populations. Those regions do not have a small grid for any family so that they can have the sun that people would want to get.”
Brockway and colleagues studied Pacific Gas and Electric and Southern California Edison, two weapons in California, the state-owned manufacturer most solar energy in the country. PG&E workspace From Mount Shasta south to Santa Barbara, right SCE service section covers the Los Angeles County, Orange County, and San Bernardino County, as well as the border with Nevada. He chose the two most important areas because he uses the most electricity in the state. All of them have very high and low altitudes, depending on the population, and one provides power to 30 million people.
The researchers compared its map of “electricity,” with the electric current that applies to each region, calculating the population and ethnicity of the region. He then calculated the number of areas that would be needed compared to the rooftop terraces and divided them into adjacent areas.
For decades, an electric grid has been used to send electricity to one side — from an electrical plant, through power lines, to a home or business. But homeowners have begun to generate electricity and send it elsewhere. In affluent and western areas, where solar power has been on the rise in recent decades, the need for resources has made it easier to do both. Brockway says: “Those who have adopted the first children are more likely to be white and to earn more than those who donate.”
But this is not the case in a few places, where the roof of the sun is not common. For example, take transformers that connect power lines to every home or business. The old ones are not built to carry extra energy that is generated from the roof of the house on the other side. Any other output can be converted to heat, which can damage or damage the transformers. Brockway says: “Every time you move electricity from one location to another, either from solar energy or through a grid to charge something, there will be more electricity passing through the lines.” The line, he continues, “is only able to deal with a large amount of time.”
Such inclusion could also make it harder to pay for electric vehicles at home, says Mohit Chhabra, senior scientist at the Natural Resources Defense Council, and this will make it harder for the U.S. to switch from electricity to EV cleaners. “The fact that the grid is not ready to reach the level of power we want is not a good thing,” Chhabra said. “We don’t want black people and low-income people to be unable to return their cars to or near their home.”
