Question
Assertion - Fossil fuels will run out at some point in the future.
Reason - Fossil fuels are non - conventional sources of energy.
- Both A and R are true, and R is the correct explanation for A.
- Both A and R are true, but R is not the correct explanation for A.
- A is true, but R is false.
- A is false, but R is true.
Hint:
Fossil fuels will run out at some point of time in the future and they are a conventional source of energy.
The correct answer is: A is true, but R is false.
- The depletion of fossil fuels is estimated to occur this century. Coal may last for up to 114 years, whereas natural gas can last for up to 53 years for oil.
- However, the demand for renewable energy isn't high enough, therefore we may quickly deplete our supplies.
- The most popular energy source is oil. About 90% of the world's commercial energy output is made up of coal, petroleum, and natural gas, while just 10% is made up of hydroelectric and nuclear power.
- When we can't use an energy source again after the first time, we refer to it as a "conventional source of energy" or a "non-renewable energy resource."
- They dominate the traditional energy landscape. Among these are nuclear power, coal, oil, and natural gas.
