Are you people serious? "Horse and buggy"???
There are scads of things that can be implemented now that,
even if imperfect, are so much better than what we currently have. Discussion of reverting back to pre-industrial technology is disingenuous at best, and an outright strawman at worst. Do you really need a list of existing viable technology that's better than snorkeling oil out of the Middle East or sending more fly ash into the air? Ok. I'll give you an
extremely abbreviated one.
1) Natural gas. Build more gas fired plants rather than coal ones. Still releases green house gases, but it does so with virtually no mercury or heavy metal emissions, and the green house gas emissions are 50% (or better) lower than coal fired plants. We've also recently developed technology to go after gas deposits in North America that were previously unrecoverable. Look up unconvesional gas plays re: shales. Upped our estimated reserves quite a bit. The recovery process is also significantly less environmentally destructive if done right.
2) Nuclear fission. Duh. And the reactors we have now are using 40 year old technology. New plants using liquid metal cooled fast neutron reactors (lead-bismuth eutectic as pioneered by the Idaho National Lab is my favorite) have the potential to address both fuel efficiency and proliferation issues.
3) Wind and solar. Imperfect, inconstant, not always there during peak load, yeah yeah yeah, it STILL can supplant the existing power supply and reduce the amount of power that has to come from non-recoverable sources. And improvements to temporary energy storage technology are reducing the severity of even that issue.
4) Better emissions post-processing on existing equipment. Emissions control technology has seen huge improvements over the last few years. Start using it now rather than later. It'll never happen without regulation! But if there is a way to reduce the amount of toxins our plants and refineries pump into our air, shouldn't we be doing it?
5) Geothermal. Do you have any idea how many oil and gas wells have been drilled in the continental US? How many of those have been plugged and abandoned because the productive zones "watered out?" Do you know what that means? It means those zones were producing so much water that they weren't getting an economically viable amount of hydrocarbon from those wells anymore. In a lot of cases, the bottom hole temperature of those "dead" wells is over 300ºF, and they were shut off because they were producing water. Hot water. That's practically screaming for someone to step in and put a geothermal turbine on it. But, despite that, it has only been done in a couple places, usually by university research groups.

Geothermal electrical power conjures images of volcanoes, geysers, and hot springs, of which only hot springs are present in Texas, specifically in the Trans-Pecos region and some areas in South Texas near the Rio Grande. However while Texas does not have sufficiently hot shallow geothermal resources of the type mentioned above, it does have literally tens of thousands of oil and gas wells that have drilled sufficiently deep to reach temperatures of over 200, 300, and sometimes 400ºF within well bores. The oil and gas industry has generally considered these high temperatures, and often the water found behind pipe in these formations as a major liability when in fact this hot water is an undeveloped energy asset that can develop out of the existing oil and gas industry. Similarly the existing geothermal industry tends to be unaware of high temperatures and thermal gradients, documented permeability, porosity, and abundant formation brine that exist within deep sedimentary basins, as recognized by the oil and gas industry. Although many of the same subsurface engineering and geoscience techniques are used in both industries, each industry has focused upon specific geological environments for entirely different energy goals. Thus the oil and gas and the geothermal industries are like brothers who rarely speak to each other, which in this case is a detriment to both.
That's an extremely abbreviated list of stuff that's out there right now. Today's technology, not some "maybe someday, with enough money and research we'll be able to-" Today. Now. It just needs to be implemented. It's much better than building more coal plants. And there are certainly plenty of people out there right now who could use the work.
