Energy isn't getting any cheaper.
Stop. Fact ignored. Solar energy prices fall 9% per year continuously. The amount of energy available from the sun is extreme, you can power the consumption of a US suburban family's life off of the energy hitting their roof with 20% efficient (typical) solar. The issue is mainly a manufacturing/cost reduction issue.
There is nothing else. Fossil fuels were a one time windfall for humanity. We squandered it and there's nothing we can do about it.
Using gasification and synthesis technology, we can foresee many potential solutions, including the diverse schemes that have been proposed and demonstrated for the conversion of CO2 and H2O in to oil using solar energy.
But the OSS community went and said Ohh look their Bad lets make GPL3 that stops these evil money making people from using OSS in that way.
Because we don't care about market share. We don't give a damn about companies using our software. We care about freedom, of us and our users. Suppose you fought for freedom and democracy, and as an ancillary effect, painted stuff blue. Then a world dictator offered to paint the whole world blue. Would you want that? No, because you really don't care about painting stuff blue (having people use Linux). What you really care freedom and democracy (freedom to modify software), which is incompatible with the existence of the dictator. What good is having a free and open system if you can't make use of your freedoms?
At work I had to be sure I never imported a GPL Library, because the rules would conflict with the companies business model.
Yes, it's a shame you can't take software without paying for it. However, IANAL, but for the most part this is ok with LGPL'd code. It really depends on the details, but LGPL'd libraries, (most useful libs are LGPL) are not GPL'd. You also can call out to a GPL'd program within proprietary code, AFAIK. For example, you could run a GPL'd "ls" shell command and read back the results and that would be ok.
The long answer, nature has stored solar energy over millions of years in this nice carrier called hydrocarbons. I call them nice because they are very energy dense, lack chemical reactivity almost completely.
At 0.00000000001% efficiency. Since you don't understand that the sun hits earth with over 1000 times more energy than a planet of 10 billion Americans, or that my friends drive to work on solar energy hitting 11 foot by 11 foot squares on their roofs, it's not even worth responding to the rest of your derivative, pseudo-intellectual post.
Happiness is a positive cash flow.
