They banned growing alfalfa in their own country as it wastes too much water. Smart guys; you can live without oil, but not without water. https://www.theguardian.com/us-news/2019/mar/25/california-water-drought-scarce-saudi-arabia It's ironic because alfalfa is drought resistant because of its deep roots. We have around 200 acres of it, and though rainfall was scant for many years until 2019, we still had a good yield. Obviously you don't have the same moisture reserves underground in saudi arabia as you would in South Dakota. Oh well. 1 Quote Share this post Link to post Share on other sites

It can run any ICE vehicle including ships, locomotives, and specially designed airplanes. High oil prices would eventually force more rapid adoption. Natural gas will also be the largest fuel used to produce electricity for all uses including electric vehicles. It is the cleanest and most economical fuel to use for heating in cold climates or to produce electricity for air conditioning in hot areas or seasons. I disagree.

They seem to make economic sense there. There are few fantastic vistas to ruin in those areas and few people. I do not like seeing them in picturesque areas around the country or world though. I would like to see them far enough offshore in the Great Lakes so they were beyond the horizon, same with our ocean coasts. There is plenty of wind there. They sure beat coal and seem much more successful than solar so far. Solar is also unsightly, but cannot be seen as far away. I can't figure out why it isn't commonly used on large big box buildings and warehouses. I was hoping that the thin solar and paint solar would work out. Solar shingles also. We will see what kind of impact it can have. It is now mandated on new California homes supposedly, but I am not seeing it going on the roofs. There are hundreds of thousands on few half million dollar homes going up near where I am right now. 2 1 Quote Share this post Link to post Share on other sites

Doing wonders for Australian economy and helping reduce CO2 at same time, I just don't believe it always cheaper than solar or wind. Certainly not here. Domestic NG price went thru the roof when our LNG exports tripled. They call it "world parity pricing", and I suspect US will suffer same fate if u build as many LNG plants as planned. Also, I think there is a risk that China will not want all the extra supply the world is offering, in which case US LNG may be repeat of Shale oil disaster.

Well, someone just posted on youtube the "NEW" version 3 Tesla roof.... $85k, 25 squares(average house), 17 DAYS to install, 12KW, 1 powerwall + pay for extra power wall. So, +$90,000. They also got the discount by owning two Teslas. So much for the new and "improved" quick installation and cheaper cost. Can buy an aluminum roof good for at least two hundred years, 12KW panels, a Tesla 3 performance, and 2 power walls. You have to be super dense to get the solar shingles. 1 Quote Share this post Link to post Share on other sites

Have a good one Outside of the walls of a lunatic asylum an economy with a balance of trade surplus is generally considered to be successful. While Germany's economic growth has been slow over the past year its growth rate has been reasonable for a large mature economy in the last decade. The Coronoavirus, if you read what I said was suggested as being the final push into a proper recession (where many countries are currently heading anyway).

Have a good one According to this the 1st half of 2019 saw $120bn globally spent on renewables (excludes large Hydro) In 2017 it peaked at approx. $160bn. https://www.pv-magazine.com/2019/07/11/global-renewables-investment-fell-in-the-first-half-of-this-year/ Against the size of the world economy which is about $82 trillion this is nothing. So basically 0.15% of economic output is going into renewables some which will be replacing what would have been spent on conventional fossil fuel based generation anyway. Based on the above there is no panic and based on that expenditure the world will be using fossil fuels for a long time yet. I'd be interested to see how that expenditure compares with combined investments into oil, gas and coal. 2 Quote Share this post Link to post Share on other sites

And Natural Gas is a really good half-way solution that can manage both base-load and peaking duties. It's unlikely that we'll get away from NG anytime soon unless surprise technologies module nuclear happen to take off. With the Saudis and their water problems. Because they can't afford plants that remove aquifer water, they have been experimenting with algal and halophyte bio-kerosene as a cash crop. Both of those allow for salt-water hydration, saving fresh water for human consumption and hopefully lowering airlines' carbon output. 1 2 Quote Share this post Link to post Share on other sites

If the supposed over supply disappears and the price goes up to a reasonable level, you’ll see much more exploration, onshore and off, and more conventional oil will go to market.

Very, little change in equilibrium or kinetics (slightly lower capacity, slightly faster rate of change). Just think of temperature in its true unit (Kelvin). Half degree C of change near room temperature is 293.15K versus 293.55K (about 0.14% change). However, with CO2 this becomes more complicated than an ideal gas due to its acidic properties and the bicarbonate buffering system (pKa and Ksp constants (eg.g carbonate rock) also change a bit with temperature).

You’d need a specialized electrician, not a mechanic! EV’s may be conceptually a good idea, but operationally, considering service after the sale, availability of parts and ability to go somewhere other than ‘around town’...they have a long way to go (pun intended).😂 Quote Share this post Link to post Share on other sites

This is a really crucial point. What we need is ENERGY to run machines. It can come from any fossil fuel or biologically produced fuel. There is no shortage and I cannot see any coming for a hundred years or beyond. Meanwhile let the other renewables do whatever they can economically. Just use the best available options. This requires the ability to think rationally and to examine all options rigorously and completely while maintaining an unbiased view. P.S. You do not need a different engine to use natural gas you just need different fuel injection and small modifications. You do need different fuel tanks which are superior to the old heavy steel ones.
