Source: Switching to electric cars is key to fixing America's 'critically insufficient' climate policies | Dana Nuccitelli | Environment | The Guardian Carbon pollution from electricity is already falling fast But the power sector is already rapidly decarbonizing because coal can’t compete in the marketplace. In some regions, new wind and solar with battery storage have already become cheaper than continuing to operate existing coal plants, and the International Renewable Energy Agency has concluded that by 2020, “all the renewable power generation technologies that are now in commercial use are expected to fall within the fossil fuel-fired cost range.” American power sector carbon emissions had exceeded those from transportation from 1979 until 2016. But because coal power plants have rapidly been replaced by natural gas and renewables, US power sector emissions have fallen rapidly since 2007, and are now below 1989 levels. US carbon pollution from transportation, on the other hand, has been on the rise since 2012. It remains higher than in 2000, nearly 20% higher than 1989 levels, and has surpassed power sector emissions. . . . I'm a little uneasy that the first two paragraphs have political content but the rest has useful technical data. We'll let the moderators figure it out. Bob Wilson
Well, that's great to realised that source pollution has really reduced. But to balance the greenhouse gas pollutions, the major source of carbon emissions right now, are pollutions from mobile sources, such as vehicles. To offset this scenario, the gradual shift from fossil powered applications to renewables, might take a longer time to offset it, considering people's continued skepticism of range on EVs, and all that. Meanwhile, according to the article, gasoline PRI WS are falling again, and Americans somewhat are interested in more efficient gasoline powered vehicles. Let's see how the switch to renewables, and its contributions to the target global 2@°C would have. Dxta
