Energy conservation refers to efforts to reduce energy consumption. Energy savings can be achieved through increased energy efficiency, combined with reduced energy consumption and / or reduced consumption from traditional energy sources.
Energy saving can lead to increased financial capital, environmental quality, national security, personal safety, and human comfort. [Citation needed] Individuals and organizations who consume Use energy to directly select energy conservation to reduce energy costs and promote economic security. Industrial and commercial users can increase energy efficiency to maximize profits.
By reducing emissions, energy conservation is an important part of mitigating climate change. Energy saving facilitates the replacement of renewable resources with renewable energy. Energy savings are often the most economical solution to energy shortages and are a more benign environmental option for increased energy production.
1.How many types of energy sources are mentioned in the text? What are they?
Two. They are renewable and non-renewable.
2.What are the disadvantages of hydro and nuclear power?
Hydro power is limited because dams cannot be built in certain areas. Nuclear power is dangerous.
3.Why do you think the wind and the sun are called alternative sources of energy?
Because they are natural sources of power and we use them instead of non-renewable sources to get the electricity we need.
4.What types of energy does Viet Nam use most?
We use non-renewable sources of energy the most but we are increasingly using hydro power.
5.What does the professor think Viet Nam will use more in the future?
He thinks Viet Nam will use the wind and the sun as alternative sources of energy in the future
rewable:wind,solar enery,hydro,nuclear,biogas...
non rewable:coal,oil,natural gas...i think people will use it more in the future

Fossil fuels are non -renewable energy soircecs.They include oil,coal,and natutal gas.They can be used to create energy, generate electricity,or drive big machinery.Unfortunately,they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however,hydro power is increasingly used here too.
Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful.However,hydro power is limited because dams cannot be built in certain areas.Nuclear power can provide enough electricity for the world´s needs, but it is dangerous.
The sun and the wind are other alternative sources of energy.
1)What are non-renewable energy sources?
Fossil fuels are non -renewable energy soircecs.
2)What can non-renewable energy soirces be used?
They can be used to create energy, generate electricity,or drive big machinery.
3)Why is hydro power limited?
Because dams cannot be built in certain areas
4)Can nuclear power provide enought electricity for the world´s needs?
Yes, it can

- What you should do to save energy
With fast growth of civilization there is also an ever mounting need for energy. Energy may be in the form of fuels or electricity. Petrol is a liquid fuel which is used widely nowadays. But this kind of fuels is likely to be exhausted at the rate man is using it recently.
To meet the challenge, various methods have been suggested. One is to minimize the man’s demand in using the energy. Non-essential consumption should be minimized. During certain days of the year, people all over the world turn off the electricity for 1 hour to save the energy. Modern gadgets consuming energy should only be used when they are absolutely necessary.
Energy conservation is possible through modernization of plant and equipment. People should replace the obsolete equipment by the modern ones.
Energy can be saved on transport by the following methods. People should commute by the rail rather than by cars and vans. The transport must be improved with a view to sparing the energy. Cities must be planned in such a way that the commuting distance from this place to others is minimized.
In industry, many things could be done to reduce waste of energy or to economize energy. The machine maintenance needs to be tightened; heater must be utilized properly. When systems are streamlined, economy in fuel is obvious. Instead of using materials requiring higher energy, those which require lower energy should be used.
We hope man with his ever rising urge for existence will cope up with this urgent problem and find alternatives.
