There are many elements needed to secure economic growth. Certainly, people must be politically free to innovate, invest, build, and create things, and they must be incentivized to do so by knowing they can keep the rewards for their efforts.

The relationship between carbon consumption and human well-being is causal, not coincidental.

I own a small aerospace company that does some business with the U.S. government.

America is a country defined by a set of ideas, and when people choose to accept those ideas, they should be able to become Americans, as fully so as any - and perhaps more so than most - regardless of how recently they or their ancestors arrived upon our shores. This is the true American tradition, which as conservatives we must defend.

In any economy, the entire population is supported by the part of it that is working. All other things being equal, it thus follows that the most attractive acquisition a society can have is a young adult, whose childhood and education has already been paid for, but whose entire working life still lies ahead.

The bedrock foundation of any rational immigration policy should be to benefit America rather than benefiting potential or existing immigrants, or any other specific group, whether favorable or antagonistic to them.

Some conservatives say that whether it's popular or unpopular, imposing strict limits on immigration is the right thing to do, and it must be defended.

No one can prevent hurricanes, but prosperous communities are much better able to withstand them than poor ones.

Weather systems are natural heat engines, and like all other heat engines, both natural and artificial, they are driven not by temperature per se, but by differences in temperature between one location and another.

In the wake of the disaster caused by Tropical Storm Sandy, various allies of the Obama campaign have rushed to claim that the event was caused by anthropogenic global warming, thereby justifying the president's program of crushing the economy with regressive carbon taxes, a supposedly necessary measure to prevent future bad weather.

The EPA must be forbidden to seize or destroy the property of any person until and unless such person has been found guilty of a crime in a court of law.

From 1859 to 1971, the U.S. oil industry grew virtually continuously, in the process serving mightily to drive our economy and win our wars. But that growth was stopped dead in 1971 and sent into decline thereafter, as the advent of the EPA and the accompanying National Environmental Policy Act made it increasingly difficult to drill.

As one of its first acts after coming into existence, the EPA banned the vital pesticide DDT.

The EPA could act to open the transportation-fuel market to vigorous competition from natural gas as well as coal, biomass, and trash, by legalizing methanol. This would force oil prices down, expand the economy, and create millions of jobs.

The natural-gas industry is screaming for new markets, and there are only two sectors where these can be found: transportation and power generation.

In addition to virtually banning methanol outright, the EPA has created regulations to prevent cars from being modified by small businesses to optimize their performance, including through the use of methanol.

We need to improve our horrible position within the petroleum game by eliminating the EPA and other crippling bureaucracies that have turned the U.S. from the game's biggest winners into its worst losers.

Despite being bailed out - in some cases repeatedly - by the public purse, the automakers have shown little public spirit.

Trillions of dollars in out-of-control entitlement spending cannot be remedied by cuts in NASA, or even in the entire discretionary budget, defense included. Rather, the financial bleeding needs to be staunched where the hole is and nowhere else.

The American people want and deserve a space program truly worthy of a nation of pioneers.

When people have their own money at stake, it's a lot easier to find and settle on practical, no-nonsense solutions to engineering problems than is ever the case in the complex and endless deliberations of a government bureaucracy.

In August 1994, I was invited to have dinner with House Minority Whip Newt Gingrich. At that time, I was a senior engineer working for Martin Marietta Astronautics in Denver, where I had been responsible for inventing a new plan called 'Mars Direct.'

Every dollar cut from the price of oil weakens the enemies of freedom and strengthens America.

Every dollar added to the price of oil weakens America and strengthens her enemies.
