In the world there are many types of energy sources, but I think wind energy is the most popular. 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.

Solar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.
Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency.

rewable:wind,solar enery,hydro,nuclear,biogas...
non rewable:coal,oil,natural gas...i think people will use it more in the future

Renewable energy describes a collection of energy technologies i.e. solar, wind, geothermal derived from sources that are never-ending and can be replenished time after time. Most countries across the world heavily depend on fossil fuels (oil, coal andnatural gas) as sources of energy to power their economies.
Fossil fuels are non-renewable forms of energy, meaning, they utilize limited resources that will ultimately deplete, hence, driving up overall energy costs. These very countries have responded to the threat by stepping up campaigns to embrace renewable forms of energy like solar and wind

When you flip on a light switch, the energy that brightens your light bulb may come from one of several potential energy sources. Different energy sources have varying advantages and disadvantages that don't just affect your utility bill but that may also have a global impact on air quality and environmental degradation.
Wind EnergyGiant wind turbines have begun to appear across North America. As wind hits the turbines, they begin to spin, and the resulting spin generates electricity that can power businesses, homes and other outfits. It provides energy without emitting greenhouse gas emissions. It's also very low-cost in the long run, as the U.S. Department of Energy estimates it to be one of the cheapest forms of renewable energy available, and it's inexhaustible as well.
However, some anti-wind activists argue that wind turbines are ugly, noisy, and dangerous to local bird species that may fly into the turbines, according to Middlebury Schools.
Solar EnergySolar energy captured by solar panels is a limitless form of energy, as the earth is bombarded with extreme amounts of solar energy every day, according to the National Renewable Energy Laboratory. It's also clean, producing no carbon dioxide, and is very low-maintenance, since solar panels have no moving parts.
Unfortunately, the National Renewable Energy Laboratory says its high installation cost makes it up to four times more expensive than the cost of electricity from a standard utility company. For optimal operation and maximum energy production, it requires year-round sunny weather and is very expensive if repair is necessary, according to the U.S. Environmental Protection Agency. Fossil FuelsFossil fuels like coal and oil are the most widely-used energy source in the world. It's typically the most plentiful, easily accessible and cheapest form of energy, according to Iowa Public Television.
However, Southern Polytechnic State University warns that fossil fuels are limited and will run out one day. Fossil fuels also endanger the environment due to the mining process and the greenhouse gas emissions produced while burning the fuel. Additionally, they may contribute to harmful side effects like air pollution and acid rain.
BiofuelsBiofuels are made from corn, sugarcane and other crops. Ethanol, widely used as a gasoline additive for powering cars, is a biofuel. It's renewable, grown domestically for greater energy security, and often produces less greenhouse gas emissions when burned, according to the National Center for Environmental Economics.
Unfortunately, growing the crops needed for biofuel may pollute the earth's soil and waterways due to farming processes and side effects like fertilizer runoff. Using crops for fuel may also use up vital food crops, and this can drive up global food prices.

Solar energy is a renewable source of energy because it comes from the sun. It's clean and safe but it's unpopolar now.
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.
