Barack Obama said his Clean Power Plan would protect America's economy and health. He wants America to switch from coal to renewable energy. Power plants must cut carbon emissions a lot by 2030. He said: "This is our moment to get this right and leave something better for our kids….We may not be able to reverse it."

Obama said the plan will make the USA healthier. There will be fewer deaths and heart attacks each year. People will be sick less. America could save $34 billion a year on health. Not everyone agrees with the plan. Jeb Bush said it will, "throw countless people out of work, and increase everyone's energy prices".
