00:01 Hello students in this question.

00:02 We are given that the most of energy most energy comes from renewable sources.

00:06 So this statement is false.

00:10 Why is it false is because we have the data set so we have cold which is the most prominent used used material for energy.

00:21 So that is 38 to 40 percentage globally and then we have natural gas, which is also not renewable.

00:30 So that is 23 to 25 percentage and we have oil which goes to 3 to 5 percentage.

00:36 These are the non -renewable sources.

00:39 Now the renewable sources which are used is hydro power.

00:44 So that is used to 16 to 18 percentage.

00:46 Then we have wind power which is used as 4 to 5 percentage solar we use to approximately 2 to 3 percentage biomass is used as 9 to 11 percentage.

01:04 So this is a renewable part and this is a non -renewable part.

01:09 So the most abundant use of resources.

01:11 The first thing is called.

01:13 Second thing is natural gas.

01:15 Third thing is hydro.

01:17 This is first second third and then we have wind fourth and then we have oil which is fifth and then solar sorry biomass is also there.

01:28 So that is the fifth one fourth one fourth one is biomass.

01:33 This is fifth and this is six and this is seventh.

01:37 So the third fourth seventh and fifth fifth ranks are holded by renewable and one second and sixth rank is hold by non -renewable energy sources.

01:48 So this statement is force...
