I doubt that there are many today who doubt that the climate is changing. Some of us just tend to look askance at people who demand that one nation pay for the remediation AND explain that a trillion dollars later, the impact will be negligible Link to comment Share on other sites More sharing options...

Doug1029 Posted April 17, 2019 #6 Share Posted April 17, 2019 Considering that we could just move to higher ground, one wonders if the expense is justified. Doug Link to comment Share on other sites More sharing options...

Some of us just tend to look askance at people who demand that one nation pay for the remediation AND explain that a trillion dollars later, the impact will be negligible Transition to clean energy will SAVE money, not cost money. Wind is cheaper than any form of energy except gas-fired turbines and solar is rapidly closing the gap with oil. The US could transition 62% of its more-expensive energy-generation to wind and save tons of money. We might have to spend the savings on transitioning the rest, but there will be technical advances before we can get that far that will cut costs further. Geoengineering/terraforming has a long way to go. It is not now cost-effective. There are some promising ideas, such as sequestering carbon in basalt formations, or sequestering it in forests. There are some ideas on making fuels from CO2. Growing plants and/or algae could be used to produce fuel and/or collect carbon for sequestration. Paper could be buried in dry landfills. Except for paper, which we are already doing to an extent, the current costs are quite high. We will find cheaper ways of doing this before we actually start industrial-scale implementation. We can do this in a cost-effective way if we do the research first. Doug Link to comment Share on other sites More sharing options...

When India and China get on board and help share the burden of the initial "investment", I'll be happy to support any sane plan that doesn't crush our economy. This country is $22T in debt already.

When India and China get on board and help share the burden of the initial "investment", I'll be happy to support and sane plan that doesn't crush our economy. This country is $22T in debt already. India and China are already on board. For India it's a choice between affordable wind power and sitting in the dark. They need more electricity and wind is the obvious choice. China is doing more than we are: the Three Gorges Dam was built to provide pollution-free power. China has the world's largest workforce dedicated to the transition to clean energy. Of course, China let things get pretty bad before they started doing anything. They're playing catch-up right now, but at the current rate, they will close the gap and reach a clean-energy economy before we do. If our country wasn't dedicated to the endless war in the Near East, we'd have several trillion dollars less debt. Hurting yourself just so you can hurt someone else is the very definition of insanity. But seriously. The transition to clean energy will be easily affordable. Eventually our existing coal and oil plants will wear out. Once it is no longer economical to repair them, we can replace them for cheaper, cleaner ones. Then just link those new wind farms with a new grid system to carry power from where the wind is to where it isn't. We already generate 6.4% of our energy from wind. Why not ten times that much? As of right now, geoengineering and terraforming are not something we can do on an industrial scale. We need a lot more research into this. We have about ten years in which to do that research.

Ocean systems may end up being too expensive simply because you can't build one that will survive the storms and still be cost-effective. In that case, something else, like a combination of wind and solar, maybe with some hydro thrown in when it's available. Sounds like you started implementing systems before you had a system ready to implement. One question: What is your current breakdown for energy generation by source?

tmcom Posted April 20, 2019 #12 Share Posted April 20, 2019 I believe 1.7% wind/solar and the rest hydro and coal, (mainly coal). Link to comment Share on other sites More sharing options...

So you're well behind us, then. We're at 6.4% as of the end of 2017. Doug Link to comment Share on other sites More sharing options...
