What is the #1 energy source used in developing countries?
Non-hydropower renewables are expected to increase their share of the total electricity supply mix from roughly one percent to four percent during that period. Overall, however, coal will continue to dominate and account for roughly half of the total production of electricity by developing countries in 2030.
What is the main source of energy on Earth?
the sunThe energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun, and sunlight can also be used to produce electricity from solar (photovoltaic) cells.

Why is it important to use less energy?
Financial savings – buildings that operate more efficiently have a reduced energy demand. That means lower operating costs. Reduced carbon footprint – by generating less energy, the buildings emit fewer greenhouse gases.
Why do developing countries use more energy?
Energy consumption is highest at the moment in developed countries and countries with high populations. This is due to a high concentration of industry, high levels of car ownership and high domestic usage from homes filled with appliances.
What are the 3 largest sources of energy consumption in the world?
In 2014, the share of world energy consumption for electricity generation by source was coal at 41%, natural gas at 22%, nuclear at 11%, hydro at 16%, other sources (solar, wind, geothermal, biomass, etc.) at 6% and oil at 4%. Coal and natural gas were the most used energy fuels for generating electricity.
What is a disadvantage of renewable energy?
One disadvantage with renewable energy is that it is difficult to generate the quantities of electricity that are as large as those produced by traditional fossil fuel generators. … Renewable energy often relies on the weather for its source of power. Hydro generators need rain to fill dams to supply flowing water.
