I would love to have peace on earth, and clean oceans and rivers, no pesticides or GMOs.
All of what you mentioned is possible if we human beings would be reasonable, data driven, logical, and compassionate...
Free energy and no pollution. We have to deal with reality at the moment, which means solar is more expensive than coal, and wind even more expensive, not to mention it kills way too many birds.
Solar is more expensive but that is just an economic reason that can be overcome with technology, manufacturing and in and of itself isn't a death sentence for solar. Solar can be competitive in the right markets and areas. Especially if it is "part" of an overall solution. As for bird deaths, that is not even remotely a consideration given the amount of species we obliterate from the planet in our search and production of fossil fuels.
Hydroelectric is not a good option, as seen in California recently..
You don't understand science or technology very well. Please do some research. Hydroelectric is a SUPERIOR method for producing electricity. In fact, there are some great proposals out there that use Ocean Currents that could generate all the power we would need to power the entire US. If we took what we spent on the Iraq War (literally a trillion dollars) we could have built up "underwater wind farms" along the Eastern and Western shores and have more than enough electricity to meet the ENTIRE NATION'S energy needs.
It would be an enormous engineering feat, but it is doable. And I don't mean pie-in-the-sky dreamy doable, I mean actually plausible and achievable based on our current levels of technology and manufacturing ability.
Maybe we can change over in five or ten years as the technology for batteries and solar panels gets better and cheaper.
Please take a second and think about the technological progression mankind has underwent in the last 120 years.
120 years ago there was no car, no airplane, no telephone, no electric devices.
In the span of 120 years we literally went from riding on horses and steam trains and boats to landing on the freaking moon.
THe computing power in a typical phone you can buy for $20 is a million times (yes one million) more powerful than the computers used to land a craft on the moon. We've built buildings that almost touch the sky, boats the size of small cities, we've done so much....
So this notion that our current energy problems are somehow too hard to solve is ludicrous and absolutely ridiculous.
The reason is simple, we are economically addicted to oil and fossil fuels in much the same way a heroin addict is strung out on drugs. The solution isn't hard, in fact the solution is known... but much like a heroin addict we just can't quit and so we make excuses.
All we need to solve our energy problems in the US is the same commitment and focus we had in WWII or the space race.
Here is a quick and dirty solution:
#1 Create colossal "underwater wind farms" along the Eastern and Western Seabeds utilizing ocean currents
#2 Use electricity generated from #1 to put the entire nation on an electric energy grid
#3 Also use Solar and Wind Technologies
#4 Also use Nuclear reactors (yes, nuclear, that's right)
#5 Electricity from 1-4 can be used to power clean production of hydrogen
#6 Cars will be electric for the most part, only certain vehicles would require traditional fuel (namely construction equipment)
Cost of the above would probably be around $1trillion dollars, but truth is, we spend that much on war and defense and corporate subsidies.
....Gasoline, diesel, and aviation fuels are going to be around for a long time to come. We do need to find ways to burn them more efficiently however.
I think that we can reduce our consumption of fossil fuels by 90% - 95%. Aviation and Construction equipment will need to use diesel (or jet fuel equivalent) for the foreseeable future. It might be possible to use nuclear reactors to obtain the same level of power but obviously that generates other problems
High tech won't solve the problem, only low tech will. High tech will ensue that only the few will benefit, having priced most out of the clean energy market. A good example is the health care/health insurance problem. The (low tech) answer is simply better health, but such an approach is unthinkable today.
The mistake I think you are making is not understanding that all high tech eventually becomes low tech over time.
In 1980 one megabyte of memory cost $700.
In 2017 one megabyte of memory costs a fraction of one penny.
In 1925 how many people flew in airplanes for a vacation?
In 1970 how many people flew in airplanes for a vacation?
In 2010 how many people flew in airplanes for vacation? (sorry couldn't dig up data but I'm sure you get my point)
If we seriously and earnestly tried to solve this problem we would solve it inside of 20 years.
But the hard truth is simply that the people in power and the system in place is too strongly tied to fossil fuels. So the truth on this matter has been obfuscated so much that the populace believes this problem is unsolvable when in reality, it is solvable with our existing technology and would take us 20 years to implement a workable and feasible solution in stages and phases.
