Ans: The ruins of two ancient cities, Harappa and Mohenjo-Daro (both in modern-day Pakistan), and the remnants of many other settlements, have revealed great clues to this mystery. Harappa was, in fact, such a rich discovery that the Indus Valley Civilization is also called the Harappan civilization.
Here's for one of them:
Type: Nuclear
Extraction: Uranium (the fuel for nuclear energy) is typically mined using open pit or sub-surface mining. Australia, Canada, Kazakhstan are where the world's largest deposits are.
Benefits: Low cost (if you don't count building the power plant), reliable (unlike wind & solar energy which comes and goes, nuclear is readily available), no carbon emissions, produce more energy than coal power plants (most popular energy source), no air pollutants emitted (all other nonrenewable sources, aka. coal, oil, and natural gas, release harmful air pollutants)
Risks to environment: Radioactive wastes require to be safely secured away for thousands of years before they can reach safe levels, nuclear accidents can happen, mining uranium cause land disturbance, thermal pollution in nearby bodies of water or wherever cooling water is released (this can lead to dissolved oxygen levels decreasing in that body of water which can suffocate aquatic life)
Other info: Nuclear energy makes up 10% of the world's energy consumption.

Answer:
Louisiana purchase, western portion of the Mississippi Waterway bowl bought in 1803 from France by the US; at under three pennies for every section of land for 828,000 square miles (2,144,520 square km), it was the best land deal in U.S. history. The buy multiplied the size of the US, extraordinarily reinforced the nation substantially and deliberately, gave an incredible force to toward the west extension, and affirmed the regulation of suggested forces of the government Constitution. The Louisiana Region had been the object of Old World interest for a long time before 1803. Investigations and dissipated settlements in the seventeenth and eighteenth hundreds of years had given France authority over the stream and title to the greater part of the Mississippi valley.
