Answer: The sun, no only kidding! The solar energy production is a global effort in the challenge of finding renewable energy sources. The wind energy effort is also heading up the research in this department. Because underdeveloped countries receive funding for finding ways to provide electricity the answer to the production of the solar panel is the easiest to answer. There are several companies that make the different models that hold the panels and Kyocera is a definite frontrunner. Chevron is also economizing the effort and several companies strive to be the best at providing rooftop resolutions.

Answer: According to the World Coal Institute: The largest coal producing countries are not confined to one region. The top five producers are China, the US, India, Australia and South Africa. Much of global coal production is used in the country in which it was produced, only around 16% of hard coal production is destined for the international coal market.
Global coal production is expected to reach 7000 Mt in 2030 - with China accounting for around half the increase over this period. Steam coal production is projected to have reached around 5200 Mt; coking coal 620 Mt; and brown coal 1200 Mt.
