Examples & Uses of Biomass Biomass Energy Biomass is organic material that comes from plants and animals, and it is a renewable source of energy. Biomass contains energy from the sun. Plants absorb the sun's energy in a process called photosynthesis.  Burning biomass releases  the chemical energy in biomass known as heat.  Biomass can be burned directly or converted to liquid biofuels or biogas that can be burned as fuels. Examples & Uses of Biomass Wood can be burned to heat buildings, to produce heat in industry, and to generate electricity. Agricultural crops and waste materials can be burned as a fuel or converted to liquid biofuels. Land, Food, and wood waste in garbage can be burned to generate electricity in power plants or converted to biogas in landfills. Animal manure and human waste can be converted to biogas, which can be burned as a fuel. Made by Adolfo Mireles©

Renewable energy source Cleaner energy source Benefits Renewable energy source Cleaner energy source Power plants don't produce greenhouse gases Better for the environment because it doesn't require large clearing of areas Replaces fossil fuels  Decreases air pollution Creates jobs for people to  design, build, and maintain the needed technology Disadvantages Greenhouse gas below the surface could potentially migrate to the surface and into the atmosphere Construction of these plants could cause land instability High electricity cost Cost of powering the pump Circumstances in which it is the best choice... Since geothermal energy causes less pollution it's less harmful to the environment and  helps to maintain and improve it. It also helps reduce reliance on fossil fuels, so really in any circumstance it could be the best choice.

BENEFITS: Hydropower is renewable. As long as there are rivers, we can use water to turn turbines. When electricity is generated with hydropower, nothing is burned. Therefore, hydropower is “clean.” It does not pollute the atmosphere or release greenhouse gases. Electricity generated by running water is relatively inexpensive. The dams that are built to generate electricity may also control floods. Hydropower is an especially useful source of energy in nations that have a lot of rivers and the money to build dams. Canada, Brazil, Norway, and Venezuela all produce more than half their electricity using hydropower. DISADVANTAGES: Because dams and reservoirs interrupt the natural flow of water, they drastically change ecosystems. For example, the population of many fishes, such as salmon, have been reduced or eliminated in dammed waterways throughout the world. In addition, the process of dam construction damages the landscape. This damage can cause erosion as well as landslides. Dams prevent important sediments and nutrients from getting downstream. Before the Aswan High Dam was constructed in Egypt in 1960’s, the Nile River flooded every year, depositing nutrient-rich mud over a strip of agricultural land. The nutrients in the mud made the soil fertile. Now, the mud is trapped behind the dam, and farmers must use chemical fertilizers to improve the quality of the soil. CIRCUMSTANCES IN WHICH IT IS THE BEST CHOICE: Hydropower is the best choice because it promotes guaranteed energy and price stability, it contributes to the storage of drinking water, increases the stability and reliability of electricity systems, it helps fight climate change, it improves the air we breathe, it offers a significant contribution to development, and it is a fundamental instrument for sustainable development.

Tidal Energy US Usage: World Usage:

Tidal Energy Benefits: Tidal energy does not produce greenhouse gas emissions unlike other forms of energy.  Tidal currents are predictable. Knowledge of high and low tide cycles can help a tidal power plant construct an efficient system for generating electricity.  Tidal turbines are 80% efficient, which is higher than solar or wind energy generators. Disadvantages: The production of tidal energy can harm the ecology of the bay or river. And with the technology we have now, there are few place where tidal energy can be harnessed effectively.  It is important to realize that the methods for generating electricity from tidal energy are relatively new technologies, which are expensive.  Disturbs migration of living creatures in the ocean

Tidal Energy: Why it's the best choice  Tidal power is a kind of hydropower that generates electric power by converting the energy of tides. Tidal power, although not a prime source of energy currently, has a great potential to be used for electricity generation in the future. Tidal energy does not create air, water, or thermal pollution. Once a dam, barrage or tidal fence is built, the energy production is free since tidal power harnesses the natural power of tides. It does not require the transport of fuels or disposal of waste products, where as other types of energy forms releases harmful gases and carbon dioxide into the atmosphere and affecting the environment as well.

How does it work? The OTEC system looks complicated but is easily grasped when explained. The sun warms the water and the warm water is put in the transitionary and then used as electricity, drinking water, and irrigation. The benefits are that it has multiple uses, but the downside is that it can only be used in warm water places.

Solar Energy Solar energy is a good choice to replace fossil fuels since it is a highly renewable resource. It can help to reduce pollution due to the fact that solar energy releases no greenhouse gases that can pollute the atmosphere.

Solar Energy Rates Worldwide and National

Benefits- Reduced carbon footprint, lower electricity bills Disadvantages- Solar panels can be expensive. Solar panels can be seasonal in the sense of how much sunlight is available at a certain time of year.

Wind Energy Indirectly, wind energy is a form of solar energy. It describes the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power.

Wind Energy Pros & Cons: A wind turbine- is a device that converts the wind's kinetic energy, or energy of motion, into electrical energy. Wind energy operates by, the energy in the wind turns two or three propeller-like blades around the rotor. The rotor is connected to the main shaft, which spins a generator to create electricity...The wind turns the blades, which turn a shaft, which connects to a generator and makes electricity. Wind turbines are most often built in groups called wind farms. Offshore wind turbines: Average wind speeds are approximately 20 percent greater over water than over land. Costs to erect and maintain wind turbines in water are higher than for wind turbines located on land. Advantages: It's a clean power source, doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Disadvantages: Noise of the rotor blades, can be a threat to wildlife, unpredictability is a major limitation of wind energy.  Wind Energy doesn't produce atmospheric emissions that cause acid rains or greenhouse gases.

Benefits It produces fewer greenhouse gases or pollutants. Water and Heat may be only waste generated from hydrogen as fuel. Hydrogen can be stored and transported from one place to another. It is probably no dangerous than gasoline.

Disadvantages It is very expensive to produce. It is highly flammable.
