The world is lacking in an efficient transport mechanism to deliver food to places that need it, in an economical way. The world is not lacking in fuel. Natural gas in the US alone can sustain the country for the next 100 years. By then, we will have shifted from a hydrocarbon fuel economy to solar + hydro + other methods (maybe renewable hydrocarbon fuels from bio-engineered synthetically created gasoline). Already, there are technologies that use the sun's energy to create fuel from algae or perhaps bacteria. There's new technologies being perfected that will help increase efficiency of solar cells by 2x efficiency. Utilizing bio-mimicry, scientists have created bacteria that can take solar energy and generate as "bacteria poop" certain types of hydrocarbon fuels.
Again, there's no shortage of food: food prices have gone down to historical lows. Even the "high end" organics foods and such are much cheaper now (per calorie, say) than what was available in the 1970s or the 1950s or the 1920s or the 1880s or however many years one wants to go back to.
There is no lack of energy. In almost every corner of the globe, energy is cheaper and more available than ever before. Farming communities in the middle of nowhere, India (or Africa) used to have to walk tens of miles to the nearest village to obtain news, information, trade. These same rural communities are now being wired in and can actually access the same internet that we read and write into. Cell phones are available even to some of the poorest communities in the world. The cost for one hour of reading light in first world countries is almost infinitesimal: less than a penny per hour. 200 years ago, in some places, you couldn't read in the dark for any amount of money.
