The map on the right shows all the areas available for oil production.
Hydraulic fracturing involves cracking rock formations by pumping fluid into wells at high pressure, forcing oil or gas out of the rock. It’s also known as hydrofracking and fracing, and, most commonly, fracking
Environmental impacts that could occur, include air pollution, discharge waste water with toxins dangerous for human and ecosystem health, release of CO2 and CH4,, and spills that can cause great environmental damage.
Not green at all, several reports suggest that the methane released by fracking and drilling makes it worse than coal.
It can. According to the U.S. Geological Survey (USGS) re-injecting wastewater into fracking wells can cause earthquakes that are usually small but that can be large enough to be felt and may cause damage.
In just a few decades the PORTUGAL could eliminate fossil fuels and rely 100 percent on clean, renewable energy. That’s the bold vision of Mark Jacobson, a Stanford engineering professor who has produced coutry-by-country road map of how the word could wean itself from coal, oil, natural gas, and nuclear power.
