In the world there are many types of energy sources,but today, the one I will tell you is the wind energy. It is a renewable energy source, so it has many advantages. Firstly, it is not harmful to the environment, people will not need to worry about environmental problems when using it. Second, wind energy lasts forever, and like tidal or solar energy, we will never run out of it. Third, it is cost effective. There are no costs associated with buying or transporting fuel into wind turbines, like coal-fired power plants. In addition, with advancements in technology, wind energy will become cheaper, thereby reducing the amount of capital that countries have to spend to meet their energy needs. However, it also has disadvantages. Windmills will make noise for everyone nearby, causing noise pollution. Not only that, the animals around it can also be in danger. Are birds safe to crash into windmill wings? Despite the downsides, the advantages of wind power are also great. It would be great if we humans use it in the future.

Part 2:
The two main forms of energy used today are electricity and fossil fuels. Electricity is the type of energy we regularly use in our daily life. My appliances use energy for many purposes, such as heating, glowing, electricity for electronic devices, etc. Furthermore, we won't have Wi-Fi without electricity. Electrical energy is extremely important, it allows human science to develop far more than it ever did.
Part 3:
Ẻnergy is in an exhausting situation. We should turn off all electrical appliances when we don't use them. Don't waste water and electricity. Walking, cycling instead of going on transport run on fossil fuels. Everything we do today to reduce energy is very meaningful :D.

Hydro power is plentiful and it can generate a great deal of energy. However, hydro power is limited because we cannot build dams in some certain areas. Solar power and wind power is convenient and abundant but sometimes they are not available.

The main source of energy at present is fossil fuel.
Some alternative sources of energy are wave energy, solar energy, biofuels, natural gas, geothermal power, wind energy, biomass energy, tidal energy, hydrogen gas, etc.
Their advantages are that they are renewable and is most likely to never run out. Also, they are easier to find than fossil fuels. They produce little or no waste that is harmful to the environment like carbon dioxide or methane so they are more environmentally friendly. Their disadvantages are that they don't produce as much energy/electricity as fossil fuels. Another disadvantage is that they rely on their surrounding. For example, wind energy needs to be generated at a windy location and needs wind turbines that take up a lot of space or solar energy needs to be generated at a sunny area and needs lots of solar panels.
