Biden Earth Day Event Will Try to Reach Young Voters, a Crucial Bloc

President Biden will travel to a national park in Virginia on Monday, Earth Day, to spotlight his clean energy investments, with an eye on bolstering support among young voters disillusioned with their choices for the 2024 election.

Against the backdrop of the park, Prince William Forest, Mr. Biden will announce $7 billion in grants to fund solar power for hundreds of thousands of homes in primarily disadvantaged communities, according to the White House. He will be joined by future members of the American Climate Corps, a new work force for young people hoping to combat climate change.

Mr. Biden’s top officials will also fan out across the country to promote his environmental policy.

Mr. Biden hopes Monday’s event can build enthusiasm among young people, a crucial constituency for his re-election bid that includes some who have expressed disappointment with the White House on economic and foreign policy matters but that also cares deeply about environmental policy.

Mr. Biden leads his Republican opponent, former President Donald J. Trump, among young voters, and many approve of his record on the environment when contrasted with Mr. Trump’s. Mr. Biden’s lead, however, is smaller than it was at this point during the 2020 election cycle, according to a Harvard Youth Poll released last week.

Young voters have emerged as a particular weakness in Mr. Biden’s approval ratings, with more than 85 percent viewing the economy as poor or fair, according to a survey by The New York Times and Siena College released last week.

Another poll, from October, found that just 31 percent of voters younger than 30 were “satisfied” with Mr. Biden’s record on climate change.
