<p>dmd77; you bring up a very valid question. The “What If” factor. Because of economics, politics, technology, naivity, supply and demand, and other factors; mankind will find other sources of energy. Solar, hydro, wind, hydrogen, nuclear, etc… will become viable renewable energy sources that will be developed. It will, because it will be technologically and economically the right thing and what is needed. Consumers aren’t going to drive less or keep their homes cooler. The demand will still be there, but the consumer will fight the high prices. (That’s where the politics come in). The energy companies and such will realize that they have milked us for all they can using fossil fuels and will develope the other sources of energy.</p>
<p>It will reduce dramatically the human factor in CO2 contribution. (Not that it will have any real affect, because I don’t believe that humans make a significant contribution); but it will assist your concern non the less. Newer energies will be more technologically friendly. It will allow consumers to not have to “Refuel” as often, it will be cleaner (For non-global warming things like air, land, and water quality), it will be cheaper, and so on.</p>
<p>Unfortunately, for the immediate future; next 10 years; there will still be financial and political issues revolving around fossil fuels. The majority of the fossil fuel is used for producing electricity and at the industrial level. Approximately 60%. There’s also the politics of some countries where fossil fuels are their major gross domestic product. (How do you tell a middle eastern country; Venezuela, and others who’s major source of income is fossil fuels that no one is going to buy it anymore? Do you subsidize them like you currently do farmers? Do you let them go backwards economically; (Which leads to war)? Exactly how do you handle these fragile economies.</p>
<p>Yes, because of economics, poltics, and technology, new energy sources will be developed. Unfortunatelly, you can’t do it overnight.</p>
