| Name another source of energy we could use.
We need nuclear energy and nuclear research. Besides, it is now clear that the real problem for the planet is not nuclear disasters, but pollution. Nuclear is greener than many alternatives. We need to shut down fossil fuel power plants. That's why electric cars are better than regular cars.
That's where green energy is essential, for reducing pollution and CO2 impact of the average men's life. But if we're talking about industry, powering data centers, space era, we need something more powerful, until we discover something new, the breakthrough that will start the new industrial revolution for real. Another consideration is that there are still unsolved problems in producing energy, wherever you look for a solution. For example, most of the solar panels active right now are not really "green", solar panels cover and "burn" a lot of soil, we still don't know the long term effects, but it is known that solar parks are affecting temperatures and weather around them. A recent study[1] concludes that "A growing body of studies underscores the vast potential of solar
energy development in places that minimize adverse environmental
impacts and confer environmental cobenefits (2, 10, 14, 15, 21).
Our study of California reveals that USSE development is a source
of land cover change and, based on its proximity to protected areas,
may exacerbate habitat fragmentation resulting in direct and
indirect ecological consequences. These impacts may include
increased isolation and nonnative species invasions, and compromised
movement potential of species tracking habitat shifts
in response to environmental disturbances, such as climate
change. Furthermore, we have shown that USSE development
within California comprises siting decisions that lead to the
alteration of natural ecosystems within and close to protected
areas in lieu of land already impacted by humans " [1] http://www.pnas.org/content/112/44/13579.full.pdf |
