Conventional Sources of Energy are those Sources of Energy which we have been using for a long time.
- Fossil Fuels like Coal, Petroleum - We burn them to produce heat
- Wood - We used to burn wood to produce heat
- HydroElectric Power Plants - Converting water at height into Electricity
- Bio-Mass - We used to use Cow-dung cakes as a fuel
- Wind Energy - We have been using Wind Energy to generate fuel since a long while
Let’s discuss them one by one
We burn Fossil Fuels like Coal and Petroleum to generate Heat and Electricity
Let’s look at Advantages and Disadvantages of Using Fossil Fuels
Advantages of using Fossil Fuels
- Since we have been using Fossil Fuels for our Energy requirements, our technologies (like car, train) have been made by using Fossil Fuels as a fuel
Disadvantages of using Fossil Fuels
Fossil Fuels were formed millions of years ago, and there are only limited reserves left.
If we keep using fossil fuels at this rapid rate, it will run out.
- Burning of Fossil fuels causes harm to environment and leads to phenomenons like Acid Rain, Global Warming
In addition to using fossil fuels to run our Cars and Bikes, we also use it to generate electricity.
Electricity generated by Fossil Fuels is generated in a Thermal Power Plant
In a Thermal Power Plant,
- We burn Coal or Petroleum to Produce Heat.
- This Heat is used to convert water into Steam
- The Steam rotates the Turbines
- And the Turbine rotates the Dynamo, which converts Mechanical Energy into Electric Energy
Hence, the conversion in Thermal Power Plant happens like
Another conventional source of Energy is
Hydroelectric Power Plant
Hydroelectric Power Plants are used where Water is at a height
In Hydroelectric Power Plant, Potential Energy of the Water at a height is converted into Mechanical Energy by Rotating the Turbines
This Mechanical energy is further converted into Electrical Energy
To put the water at a height, we use Dams.
Dams are formed in rivers to stop their flow, and keep it at a height.
Advantages of using Hydroelectric Power Plant
Since water in the dams will get filled by itself due to rain, it is a renewable source of energy
Disadvantages of using Hydroelectric Power Plant
- Dams can only be constructed in specific number of places, like, hilly terrains
- Large areas of agricultural and human land is submerged under water
- The vegetation which is submerged under water rots in anaerobic conditions which leads to generation of huge amounts of methane. Methane is a greenhouse gas
- There is a problem of proper displacement of people who are living in the area near the dam
