Answer:worst offender, a dirty energy source that produces less than half our electricity but nearly 80 percent of all power plant carbon emissions.
The good news is that coal is on the decline. Many old and inefficient coal plants are closing down and essentially no new coal plants are being built in the US, a trend that is driving the largest transformation of the US electricity system in half a century.
The energy choices we make during this pivotal moment will carry huge consequences for our health, our climate, and our economy for decades to come.
Right now we are moving toward a natural gas-dominated electricity system, but an over-reliance on natural gas has significant risks and is not a long-term solution to our energy needs. Like coal, it is a fossil fuel that generates substantial global warming emissions, and has other health, environmental, and economic risks.
There's a better, cleaner way to meet our energy needs. Renewable energy resources like wind and solar power generate electricity with little or no pollution and global warming emissions—and could reliably and affordably provide up to 40 percent of US electricity by 2030, and 80 percent by 2050.
To create a cleaner, safer, and healthier energy future, it's time to choose renewables first.

Answer:
Wilbur and Orville Wright were American inventors and pioneers of aviation. In 1903 the Wright brothers achieved the first powered, sustained and controlled airplane flight; they surpassed their own milestone two years later when they built and flew the first fully practical airplane.
Always working on different mechanical projects and keeping up with scientific research, the Wright brothers closely followed the research of German aviator Otto Lilienthal. When Lilienthal died in a glider crash, the brothers decided to start their own experiments with flight. Determined to develop their own successful design, Wilbur and Orville headed to Kitty Hawk, North Carolina, known for its strong winds.
Wilbur and Orville set to work trying to figure out how to design wings for flight. They observed that birds angled their wings for balance and control, and tried to emulate this, developing a concept called “wing warping.” When they added a moveable rudder, the Wright brothers found they had the magic formula-on December 17, 1903, they succeeded in flying the first free, controlled flight of a power-driven airplaine. Wilbur flew their plane for 59 seconds, over a distance of 852 feet, an extraordinary achievement for their time.
The Wright brothers soon found that their success was not appreciated by all. Many in the press, as well as fellow flight experts, were reluctant to believe the brothers’ claims at all. As a result, Wilbur set out for Europe in 1908, where he hoped he would have more success convincing the public and selling airplanes.
