Take the challenge of climate change. In just eight years, we’ve halved our dependence on foreign oil, we doubled our renewable energy, we led the world to an agreement that has the promise to save this planet.
Autonomous underwater vehicles, or AUVs, are used in the oil industry, for instance, to create maps of the seabed before rigs and pipelines are installed.
While fossil fuels — coal, oil, gas — still generate roughly 85 percent of the world's energy supply, it's clearer than ever that the future belongs to renewable sources such as wind and solar.
The use of fossil fuels-coal, oil and natural gas has affected the environment by polluting the air and water, creating toxic wastes, and causing global warming.
Yet it is hard to imagine that the merger of a few oil firms today could re-create the same threats to competition that were feared nearly a century ago in the U.S. , when the Standard Oil Trust was broken up.
