1. Hydroelectric power (HEP), solar energy, wind and tidal waves are all sources of renewable energy. Natural gas is the only source of non-renewable energy. Natural gas is obtained from fossil fuels when remains of plants and animals buried in layers of soil were mixed with sand and silt. Around 90% of the fuel’s energy can be used; hence, it is highly efficient. It is a mixture of several gases such as methane, butane, ethane, and butane. It is a cleanest gas that does not leave any residues. However, it cannot be rederived as it takes thousands of years to synthesize it.
Right option is A. Natural gas.
2. According to the US department of Energy, 85% of the energy used comes from non-renewable energy sources such as oil, coal, natural gas, and uranium.
Right option is C. 85
3. Crude oil, natural gas, and coal are formed from dead plants and animals by exposure to heat and pressure in the earth's crust over hundreds of millions of years. These fuels when burnt give a large amount of carbon dioxide. Biomass is organic matter that is used as fuel to make electricity. They include woody fuels and animal wastes. It is a renewable source of energy because biomass exists as scap wood, mill residues etc, and crops/forests will always be available.
Right option is B. Biomass.
4. Crude oil is refined to petroleum naphtha, gasoline, diesel fuel, asphalt base, heating oil, kerosene, liquefied petroleum gas, jet fuel, and fuel oils in refineries. Hence, refined oil is obtained from crude oil. It mostly contains 84% carbon, 14% hydrogen, 1 - 3% sulfur, and less than 1% each of nitrogen, oxygen, metals, and salts. Refining involves distillation, or fractionation of crude oils into separate hydrocarbons. These hydrocarbons are converted into more usable products by cracking, reforming, etc.
Right option is E. crude oil.
