The possibilities for future energy production include fossil fuels, biofuels, solar, wind, hydro-energy, geothermal, and nuclear. Each of these sources has relative advantages and disadvantages. The problem is to produce enough sustainable energy while avoiding unacceptable environmental consequences, especially climate change. Informed choices will help prevent waste, avoid unnecessary disruptions in our lives, and avoid undesirable ecological effects.

At the end of the last ice age, the earth’s average temperature increased and glaciers moved rapidly northward. Additionally, rainfall progressively decreased in Southwest Asia and Africa. Under the changed circumstances, humans were unable to sustain themselves throughout the year by hunting and foraging. The human groups, living on different continents, were forced to produce their own food, and farming began within a short span of time all around the globe.

English was originally brought to what is now called Britain by Anglo-Saxon settlers from northwest Germany, West Denmark, and the Netherlands. The language that we nowadays call English has been changed almost out of recognition by the passing of time, and even more influentially, the impact of other languages. It is estimated that words borrowed from other languages make up more than three-quarters of the English language.

In June 2014 a ‘super-smart computer’ convinced human judges that it was a 13-year-old Ukrainian boy. It was said to be the first artificial intelligence to pass the Turing test, which determines if a computer can deceive a human into believing they are interacting with another human. However, many scientists accused Eugene’s makers of cheating the system by making him a young teenager and a non-native speaker of English.

The hyperloop is a new system of super speed ground-level transportation. The concept is described as a vacuum or low air pressure tube which would allow a hovering pod to travel at speeds as high as 1200 kilometers per hour. Low friction is key to these speeds as well as being energy efficient compared to regular high speed trains. Supporters claim travel times could be shorter, compared to planes, for distances of up to 1500 kilometers.
