1. What is meant by using our energy resources in a sustainable way?
An energy resource is something that can produce heat, power life, move objects, or
produce electricity.
it means to conserve our energy resources and be aware that our fossil fuels are non
replaceable and in order to make it last. For Example, when we leave the house, we
turn off all the lights because that saves money and electricity.
2. Describe at least three measures to reduce energy consumption in your country/other
countries
1) governments can push for using more public transport like MRT and busses.
2) governments can make trains for the MRT electric based instead of based on fuel
3) make propaganda against Air Conditioning
3. Name three types of alternative energy resources.
Solar energy
-solar energy is radiant light and heat from the sun.
-provides clean and reusable energy.
-Works by allowing photons or particles of light, to knock electrons free from atoms, therefore,
generating flow of electricity.
Wind power
-wind energy is the use of air flow through wind turbines to provide mechanical power and
energy.
-wind energy is cheap and does not produce emissions like fuels.
Nuclear energy
-nuclear energy comes from splitting atoms,in a reactor to heat water into steam, turn a turbine
into electricity.
- produces Low emissions of carbon dioxide and produces lots of energy
4. Explain how these are more suitable than fossil fuels.
Renewable Energy is Cleaner than Fossil Fuels. ... Renewable energy, on the other hand,
typically emits less CO2 than fossil fuels. In fact, renewables like solar and wind power—apart
from construction and maintenance—don't emit any CO2 at all.Jan 25, 2018
The difference between the two isn’t as complicated as you may think. Renewable energy
comes from natural resources that can be replenished during an average human lifetime and
includes the following types of power
Fossil fuels, on the other hand, can take thousands—or even millions—of years to naturally
replenish
5. Explain the common disadvantage/ problems of alternative energy resources
•
Technologies that use alternative energy sources have remained to be relatively
expensive ( major influence on energy prices )
•
Still generates the pollution (May release carbon dioxide or methane )
•
May not be a permanent energy resource
•
Energy resource that is difficult to access for many people
