Renewable examples

Question 1

What is biomass? With examples

Answer 1

All biological materials which were alive before, are the source of biomass.
Ex: Wood, animals

Question 2

What is geomass?

Answer 2

A “U” shaped tube is inserted into the Earth. From one branch, water is poured, as the temperature close to the core of the Earth is high, water gets into stem. from the other branch, stem with high pressure and temperature comes out, and it turns the blades of turbine to generate electricity.

Question 3

Define Wind Generator (Wind). Formula?

Answer 3

The power is effected by density of air, area of blades, the speed of air.
Formula- 1/2P(density)AV^3
P= Density
A=Area
V^3= Speed

Question 4

Define Pumped Storage (water). Formula?

Answer 4

Two containers are placed at two diff, heights. These are connected by a pipe. The container which is placed at the higher height, has a higher gravitational protentional energy, so water flows from that to the lower container.
*When the demand is low, then water is pumped from the lower to higher.
Formula- Ep= mg(triangle)h
E= Electricity p= Potential energy
mg= Gravitational potentional energy
(triangle)= Change in height (delta)
h= Height

Question 4

Solar panels (Sun) has two types called?

Answer 4

Heating panels and Photovoltaic panels

Question 5

Heating panels?

Answer 5

The radiation of the sun is converted into heat energy, and this form of energy, turns water into stem, and then stem turns turbine to generate electricity

Question 6

Photovoltaic panels?

Answer 6

Int his type of panel, the radiation of the sun, is converted into electricity directly, as it is made up of semi conductors.
