By 2050 the world is going to use 50 percent more energy than it does today. It means that energy becomes more affordable and reliable, which leads to increase the quality of life. On the other hand about 1 billion people don’t feel this progress, because they still live without basic power services. These services run production and schools, light cities, move cars and trucks. Thanks to abundant energy the poverty rate has decreased twice during the last 25 years, millions of people have got the chance to enhance their lives.
In fact, the growing use of energy has disadvantages as well. Most of the energy is gained from fossil fuels, which lead to greenhouse gases and climate change. The only way to significantly lower carbon emissions is switching to sources that do not emit carbon.
Today we have the renewable technologies like solar and wind. They have been developed much and can be one option to a zero-carbon emitters. At the same time, a lot of various paths must be explored, which means that new approaches must be invented. Private firms will eventually improve these energy achievements, however, their work depends on different researches, which can be funded only by governments.
