WASHINGTON  — President Joe Biden persuaded Democrats in Congress to provide hundreds of billions of dollars to fight climate change.

Now comes another formidable task: enticing Americans to buy millions of electric cars, heat pumps, solar panels and more efficient appliances.

Biden faces a public relations challenge that could determine whether the country achieves his ambitious goal to cut greenhouse gas emissions in half by 2030.

One analyst says the battle will be waged “one household at a time.” Officials hope consumers will respond to tax credits and rebates when they make purchasing decisions — if they are aware of them.
