VI . Read , answer the questions . Fossil fuels are non - renewable energy sources . They include oil , coal , and natural 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 . The wind turns turbines to make electricity . Solar power can be converted into electricity . It can be used to heat or cool our houses . Although there are some disadvantages , these alternative energy sources can offer abundant amounts of clean , safe electricity . They will be valued more and more in the future in Viet Nam .
