4. Biogas creates a lot of smoke. F
5. The new energy source is not costly T
Energy is fundamental to human beings. Many poor people in developing countries do not have modern sources of energy like electricity or natural gas, with which their life can be improved.
People who live in mountainous areas have to gather wood for fuel. This takes a lot of time. For many people living in rural areas, biogas is the largest energy resource available. The main use of biogas is for cooking and heating, but it can also provide energy for public transport. As biogas is smoke-free, it helps solve the problem of indoor air pollution. Moreover, it’s made from plant waste and animal manure. They cost almost nothing.
The tendency to use renewable energy sources in developing countries is on the increase as non-renewable ones are running outệIn the future, the wind and the sun will be used as the most important environmentally friendly energy sources.

In the modern world, people depend on energy to power their everyday lives. A wide range of power-run devices and modern conveniences (1) are taken for granted, and although it may seem that we will not be in danger of living without those conveniences, the fact is that many supplies of energy are running out rapidly. Scientists are constantly (2) searching for new sources of energy to keep modern society running. Whether future populations will continue to enjoy the benefits of abundant energy will depend (3) on the success of this search. Coal, oil and natural gas are now being used widely. (4) However, not only are supplies of , these supplies are limited, and they are a major source of pollution. Therefore, the existing alternative energy sources must be improved or futher explored and developed. These include nuclear, water, solar, and wind power, as well as energy from new, (5) nonpolluting types of fuels types of fuels. Each of these, however, has advantages and disadvantages.
Read the passage below and an answer the question :
We can develop alternative sources of energy,and unless we'll never succeed.instead of burning fossil fuels we should be concentrating on more economic uses of electricity because electricity can be produced from any source of energy. If we didn't waste so much energy,our resources would last longer. We can save more energy by conservativation than we can produce for the same money. Unless we do research on solar energy wind power tidal power hydroelectric plants.... Our fossil fuels will run out and we'll all freeze starve to dealth . Many countries are spending much more time and money on research because the energy from the sun the waves and the winds last forever.we really won't survive unless we start working on cleaner safer scour of energy .
1 Can electricity be produced from any sources of energy?
Yes, it can.
2 What would happen if we didn't waste so much energy?
If we didn't waste so much energy, our resources would last longer.
3 Why are many countries spending much more time and money doing research on energy from the sun the waves and the wind?
Because the energy from the sun the waves and the winds last forever.
4 What will happen unless we start working on cleanr and safer sources of energy?
We really won't survive unless we start working on cleaner and safer scources of energy

It’s hard to (1) believe that just 200 years ago our main energy source was wood. Now we have a wealth of energy sources to choose from, including a growing range of (2) renewable energy technologies.
But what does the future hold? How can we keep (3) supplying energy to an ever-growing population? How much will it cost?
And what impact will the energy choices we make have on our living conditions and our planet?
In a report this year, the Internet Energy Agency experts electricity generation from renewable energy (4) sources to increase from 21 percent in 2012 to 33 percent by 2040. Morever, as battery technology inproves, it will be better able to support renewable energy sources, such as (5) solar and wind power.
Innovation in energy storage has already resulted in graphene technology used in batteries, which may be able to store more energy than existing lithium batteries.
