Tidal energy: -Used tides to produce energy. -This new type of energy has it's negative side, it can affect wind and tides. -But it's positive side is that it does not generate emissions of gasses causing global warming. -Geothermal energy has hydrogen sulfide gas wich smell really bad.
Solar energy comes from the rays of the sun. Solar thermal energy has two groups; Passive and Active. Passive requires no machines, but Active does. Those machines are called non-concentrated and concentrated collectors. The collectors use photovoltaic cells to convert sunlight to energy.
Wind is also another source of energy, and it is gathered by wind turbines. Wind goes through a generator turbine and comes out as energy. At first, it would take a lot of money to build and make wind turbines, but in the long run, we would save a lot of money on energy. Not only that, the wind turbines doesn’t release greenhouse gases that harm the atmosphere or cause global warming.
There are two types of solar energy; they are passive solar heating and active solar heating. Passive solar heating is a type of energy that doesn’t involve machines. It’s just as simple as opening a window for sun light to come in and heat a room. Active solar energy requires a mechanical device called a collector. There are two types of collectors, concentrating and nonconcentrating. Wind energy is produced by using wind turbines. Most of these turbines have two or three blades called rotators. The rotating of these blades has the capacity to turn a generator on and produce energy.
Alternative and renewable energy: Solar energy comes from rays from the sun which produces energy. There are two groups of solar thermal energy. Passive and active.Passive requires no machines, but active does. Flat plate is the most common plate used. Wind energy, converts the energy into rotary motion that drives the generator.
Alternative & renewable energy -wind and solar energy wind mills and solar plates are great for the earth.There is not generate emissions that cause global warming.The negative side would be the fincail issues.The wind mills cost alot of money to be created and placed in the ground.Durning a hurricane the plates can fly away.
Hydroelectric ->Hydroelectric energy uses our own natural resource, water, to produce and create energy. ->This energy can be made by dams that also benifit us because it would also manage the water levels in the rivers and water streams. ->It is cheaper because the more water that flows through the dam the more electrciy it produces. since our earth is ninety-seven percent made of water we can never run out.

Wind and Solar *Solar energy is created by the rays of sun *Passive solar heating requires no machine to collect the heat *Wind energy is gatered by using wind turbines, then converts the energy into a rotary motion that drives the generator of the turbine
Hydropowered energy is energy from water and develops 100 feet below ground, within pen stocks. It is cheap, non-pollutant, and renewable. Disadvantages of hydropowered plants are that it can fail, flood, and decreases the population of fish. Solar energy is energy from the sun and involves a solar pad that soaks up the energy from the sun. Wind energy is self-explanatory and uses turbines. When the wind blows, it activates the turbines and rotates depending on how windy it is. Tidal energy is power from tides and waves and converts it into energy. A benefit of tidal energy is that it does not create global warming and the animals are okay. A drawback of this source of energy is that it depends on tides and there is no control. There are also biomasses which can be used as energy crops. Biomass energy takes up 2/3 of land for energy crops; in turn we are less dependent on fossil fuels and oil.
Alternative and renewable energy Tidal, geothermal
Tidal energy, known as tidal power, a form of hydropower that convert energy particles. It is _Renewable _No need for fuel _Produces electricity reliably.
Hydropower uses rivers to create energy. It controls floods,irrigation, its renewable. Tidal energy uses the tides for energy. The disadvantages are that it affects the tides and the wind has to play a major part in order to do energy. Advantages are that it creates no emmissions, marine life is not affected. Geothermal uses the heat of the earth to make energy.

Wind energy: Wind energy is gathered by the wind turbines and converts energy into a rotary motion that powers the generator of the turbine. It's also a resource that never runs out.
Solar energy takes the rays of the sun and converts it into energy. The two types of solar energy are passive and active. There is also non-concentrating which are the flat plate types and concentrating. Solar Energy is a natural resource as is Wind energy. Wind energy harnesses the kinetic energy of the wind via wind turbines. Neither wind nor solar energy create radioactive/greenhouse gasses, and both are renewable.
Solar energy is constructed by the rays of the sun. There are two types of solar thermal energy: Passive and Active. Passive solar heating requires the use of no machinery and just opening up a window to warm up a room, whereas active solar heating needs machinery. An example of this would be the flat plates which are non-concentrating.
Wind energy is created from the help of wind turbines. Their rotors help harness the wind's kinetic energy. The wind goes through a generator to make energy. It takes a lot of money to make wind turbines, but in the long run it would cost less because it is a natural resource. They also do not create green house gases which are harmful to the environment.
Hydroelectricity is electricity generated from hydropower. It can be helpful by controlling flooding and providng irrigation to near crops. It can also stop the natural flow of the river and stop the migration of young fish depleting their numbers. Ten percent of the electricity used in the US comes from hydroelectricity.

Hydropower plants can control flooding but stop the natural river water flows.
Theirs some American states that produce hydropower in the U.S.: Washington, California and Oregon.
Biomass would require plants or animal maters which then would produce energy.
Other requirements are large unpopulated lands
Effect the U.S. economy at first because our currently leading suppliers from petroleum would no longer be needed and unfortunately go broke.
