looks like Trump prefers a dieing coal industry over natural gas, among other things.

I'm sure he's concerned about the affect of fracking on the environment.

Houses don't blow up from coal explosions. It is safer in that respect. It is also so cozy. I knew someone that had a coal stove and the comfort was awesome. it is just a different kind of heat.

Fracking is bad for the earth, it requires fracturing the earth to get the gas that bubbles up. It is bad for the environment, has created earthquakes in Oklahoma, yet they still keep pushing it.

Gina, you know we are not talking about burning coal for heat, right? We are talking about burning coal in big power plants to heat boilers, which in turn produce steam to run turbines, which in turn generate electricity to send out over the grid so that your light turns on when you flip the switch. As a result of the process you get smokestack emissions and coal ash, not to mention the environmental impact of mining the coal. Power generated at a natural gas plant follows pretty much the same process but it burns cleaner and the environmental issues of fracking are different than mining coal. All forms of power generation are a compromise between availability, cost, and environmental impact, even wind, solar, and nuclear. There is no 'perfect' solution.

Sometimes your electric company sends out a little flier type thing detailing where the origins of their electric production come from. I pulled out two from my Ohio Edison file for here in Northeast Ohio.

2009:
46% Coal
33% Nuclear
19% Unknown (which likely includes some natural gas, not sure why it is grouped with unknown)
1% Hydro
1% Wind

2015
45.5% Coal
34% Nuclear
16% Gas
2% Wind
1% Hyrdo
.5% Oil
.5% Biomass
.5% Other

Coal still plays a very large role in our energy needs and I believe this resource should continue to be utilized. I'm also happy that in some regions (not mine apparently) that natural gas is being used to replace coal at some power plants, that is good, a cleaner source that we can produce and utilize. But as you can see even in my area, which was big in the natural gas and fracking boom of a few years ago, coal is still the main source.

Does Trump prefer coal over natural gas? Or is it simply a realization that our electric suppliers still rely on coal to a large degree?

Doesn't the sun shine in Ohio?

Actually, Youngstown is the nearest city and I am pretty sure it has the most cloudy days in the country. I love cloudy days, most people here don't. Not many solar panels around here. The local GM plant in Lordstown has a small solar panel field...probably just for PR rather than meaningful energy production.

I thought fracking dislodges oil not natural gas? There is a tonne of natural gas easily accessible throughout the world hence the low price for natural gas.

It is used for both.

FPL here in Florida, here is what I found:

Natural Gas - 71.7 %
Nuclear - 15.5 %
Purchased power - 7.8 %
Coal - 4.5 %
Oil - 0.4 %
Solar - 0.06 %

Coal is still king (or close to it) nationwide:

https://www.eia.gov/tools/faqs/faq.cfm?id=427&t=3

In 2015, the United States generated about 4 trillion kilowatthours of electricity.1 About 67% of the electricity generated was from fossil fuels (coal, natural gas, and petroleum).

Major energy sources and percent share of total U.S. electricity generation in 2015:

Coal = 33%
Natural gas = 33%
Nuclear = 20%
Hydropower = 6%
Other renewables = 7%
Biomass = 1.6%
Geothermal = 0.4%
Solar = 0.6%
Wind = 4.7%
Petroleum = 1%
Other gases = <1%

Preliminary data; based on generation by utility-scale facilities.

https://en.wikipedia.org/wiki/Fossil-fuel_phase-out

Coal is one of the largest sources of energy, supplying 27 percent of the world's primary energy in 2006.[13] Coal also accounts for up to one-third of global carbon emissions.[citation needed] To decrease carbon emissions and thus possibly stop extreme climate change, some have called for coal to be phased out.[14][15] Climatologist James E. Hansen said "We need a moratorium on coal now...with phase-out of existing plants over the next two decades."[16]

Some nations have decreased their coal consumption thus far in the 21st century, the greatest reductions being in the United States (coal consumption reduced by 176 million metric tons per year over the period 2000-2012), Canada (reduced by 21 million tons per year) and Spain (20 million tons per year). Other nations have increased their coal consumption in the same period, led by China (increased 2,263 million metric tons per year in the period 2000-2012), India (increased 367 million tons per year), and South Korea (59 million tons per year). Worldwide, coal consumption increased 60% during the period 2000-2012.[17] As of 2012, 1200 new coal power plants were reportedly being planned worldwide, most of them in China and India.[18]

In the 2011-2013 period, the OCED group of Western European countries has increased the use of coal, attributed largely to the low cost of coal and the high price of imported natural gas in Western Europe.[19]

According to Scientific American, the average coal plant emits more than 100 times as much radiation per year than does a comparatively sized nuclear power plant, in the form of fly ash.[20]

Some believe that coal should not be phased out, considering that longer-term global economic growth cannot be achieved without adequate and affordable energy supplies, which will require continuing significant contributions from fossil fuels including coal. In this viewpoint, clean coal technology could reduce greenhouse gas emissions compatible with a low-emissions future.[21] Some environmentalists and climatologists support a phase-out and criticise clean coal as not a solution to climate change.[22] Entrepreneurs promote improved regulations and modernised technology.

No I did not know that coal is involved in generating electricity. We ought to just go to solar power, but the profits wouldn't be there to all those making tons of money off the coal and gas businesses so it won't happen. The earth has a limit on the amount of abuse it will tolerate before it fights back, with earthquakes etc.
