To produce a clean renewable source of energy we could use wind generators in the savanna's to create as much power as we needed. Also we could use solar panels with photo voltaic cells. The solar thermal energy would provide plenty of energy because of the heat.
To sustain these sources of energy would be simple enough. The wind generators would need to be checked on to make sure they are operating each day. The solar panels would be good for sunny days so that the sun can shine its light on them. the solar thermal energy would need heat to run so the day would not only have to be sunny but warm too. All of these would have to be checked on to make sure that the animals did not attack them. If the animals don't attack them then we will have clean sources of energy. These will be easy to get in because most of the materials are cheap except for the photo voltaic cells.

If Moore's law holds for the next twenty years then the computing power of computers may come close to AI. The power of computers will double every year and the price to making the equipment is steadily dropping. At this rate the companies can make the same profit from selling their product at a cheaper price than they were before. Every household should be able to afford a computer with a high processing power. The size of the computers could possibly be the size of our palm pilots and have the processing power of a full terminal top of the line computer that we have now.
Moore's law states that the power of computers will double every year and so far that law has held true for the past twenty years. the price will also steadily drop because now that machines are taking over most of the processes it cuts back on the cost because of less workers and higher efficiency. Even now scientists are working on nano-technology which will decrease the size of the chips and boards in the computer which should allow extremely high processors in smaller spaces.
