（A segment of President Obama’s speech to a joint¹ session of Congress on February 24th dealing² with energy and basic research:）

We know the country that harnesses the power of clean, renewable energy will lead the 21st century. And yet, it is China that has launched the largest effort in history to make their economy energy efficient. We invented solar technology, but we've fallen behind countries like Germany and Japan in producing it. New plug-in hybrids³ roll off our assembly lines, but they will run on batteries made in Korea.

 Well I do not accept a future where the jobs and industries of tomorrow take root beyond our borders—and I know you don't either. It is time for America to lead again.

 Thanks to our recovery plan, we will double this nation's supply of renewable energy in the next three years. We have also made the largest investment in basic research funding in American history—an investment that will spur not only new discoveries in energy, but breakthroughs in medicine, and science, and technology.

 We will soon lay down thousands of miles of power lines that can carry new energy to cities and towns across this country. And we will put Americans to work making our homes and buildings more efficient so that we can save billions of dollars on our energy bills.

 But to truly transform our economy, to protect our security, and save our planet from the ravages⁴ of climate change, we need to ultimately make clean, renewable energy the profitable kind of energy. So I ask this Congress to send me legislation that places a market-based cap on carbon pollution and drives the production of more renewable energy in America. That’s what we need. And to support, to support that innovation, we will invest $15 billion a year to develop technologies like wind power and solar power; advanced biofuels, clean coal and more efficient cars and trucks built right here in America.
