* The only energy source that can cope with the increasing demand of humans in the long run is the Sun. But before we see solar technologies on a large scale in electricity generation, they will have to become much cheaper. Solar energy systems must compete against non-renewable, environmentally unfriendly, fossil fuels on economic grounds.
* It might be easier if we really could “harness” the Sun, but that bright spot in the sky is elusive. Sometimes it hides behind clouds, and, each night, it disappears altogether for hours at a time.
* The optimal time to mine the Sun’s energy is when it’s highest in the sky, typically during the summer months when we also enjoy longer days with more average sunshine.
* A solar panel does not adapt itself to the movement of the Sun, and as the day goes on and the Sun moves in its regular path, the panel is left without a source of light.
* It’s good to know what’s going on in the world, and intentional efforts should be made to understand what common beliefs are in secular society.
* When asking people on the street the question, “What’s the biggest problem in the world?” you’re going to get a bunch of different answers.
* The world will face many challenges over the coming decades, not least among them environmental challenges.
* One-Quarter of World’s population lacks Electricity. Some 130 years since Thomas Edison’s breakthrough with artificial light, nearly a quarter of humanity still lacks electricity. An estimated 79 % of the people in the Third World – the 50 poorest nations – have no access to electricity, despite decades of international development work. The total number of individuals without electric power is put at about 1.5 billion, or a quarter of world’s population, concentrated mostly in Africa and Southern Asia. The problem is most acute in Sub-Saharan Africa, with several entire nations there effectively with no electricity. In 11 countries, all in Africa more than...
