How mobile phones can save, not waste, energy
World Economic Forum
The mobile industry is experiencing explosive growth worldwide, fuelled by almost 7 billion subscribers and an ever-growing demand for data traffic. However, the energy efficiency of mobile networks remains extremely low. Both base stations and smartphones regularly waste 70% of the energy consumed as heat. The underlying power architecture used in mobile communications still relies on outdated technology developed during the 1930s. The impact of relying on such outdated technology is huge.
U.N. Predicts New Global Population Boom
MIT Technology Review
A new analysis suggests that the world’s population will keep rising through 2100, and not flatten around 2050 as has been widely assumed. Such an increase would have huge implications, but the prediction’s reliability is debatable, given that it does not take into account future hardships a large population would likely face. According to the new analysis by researchers at the United Nations and several academic institutions, there is an 80 percent chance that the world’s population, now 7.2 billion, won’t stop at nine billion in 2050, but will instead be between 9.6 billion and 12.3 billion by 2100.
