Controlling idea
Hydroelectricity and solar thermal electricity are quite different in terms of limitation of production, environmental impacts and operation. On the other hand, they are similar to cost and maintenance.
A: First difference is: limitation of production
Explain
Hydropower is reliable source of energy
- There is always water, so hydropower can be produced every time.
Explain
Solar energy is unreliable source of energy
- Solar energy is an intermittent energy source with periods of time such as at night.
B: Second difference is: environmental impacts
Explain
The effect is from producing hydro energy.
- The fishes and plants can get the water to be alive.
Explain
The effect is from producing solar energy.
- There aren’t any effects.
C: Third difference is: operation
Explain
Producing hydro energy is more difficult than producing solar energy.
- Hydro energy must use the electricity in order to motivate the operation.
Explain
Producing solar energy is easier than producing hydro energy.
- When the sun arises and the sky doesn’t have any clouds, solar energy can be produced at that time.
E: First similarities is: cost
Explain
Hydropower and solar energy is similar to high initial cost.
F: Second similarities is: maintenance
Explain
Both hydropower and solar energy have low maintenance.
Topic sentence
Even though both hydroelectricity and solar thermal electricity are “Power”, there are many similarities and differences.
Conclusion
In the final analysis, Both Hydroelectricity and Solar Thermal Electricity still use at this point in time, we should know similarities and differences of them.
