Tidal Power:

It is a form of hydro power that converts the energy of the tides into electricity or other useful forms of power. The tide is created by the gravitational effect of the sun and the moon on the earth causing cyclical movement of the seas.It uses approximately 10% of global electricity production.

Tidal Stream Generators  is the flow of water as the tide ebbs and floods, and manifests itself as tidal current.

The turbines are mounted with a gearbox shaft which generates electricity; underwater cables carry the electricity to the shore.

Tidal Range is the vertical difference in height between the high tide and the succeeding low tide.

Tidal Barrage: it is a dam that stretches across a river estuary. Inside it are a series of turbine wheels, continuously rotated by the constant water flow as the tide rises and falls, generating hydroelectric power

Wave Power:

It is the transport of energy by wind waves, and the capture of that energy to do useful work. Ocean waves are caused by winds blowing by the ocean, the contain big amounts of energy potential. Ocean wave energy is also captured directly from surface waves or from pressure below the surface. Waves and tidal resource potential is typically given in terawatt-hours/year; Terra-watt is unit of power equal to one trillion watts. 2% worldwide

Fossil Fuels:

Natural resources such as coal and oil . Fossil Fuels come from the remains of ancient plants and animals. Main sources for modern machines. 80% of our world’s energy sources depend on fossil fuels. Disadvantage of fossil fuels are the fact that they are disappearing fast. Advantage of fossil fuels is that the sales will help the economy and technology for fossil fuels have already been built. Fossil fuels are responsible for majority of environmental issues like global warming, acid rain, air pollution, water pollution that we are dealing with today.

Solar Power:

Comes from the power of the sun. Deep inside the sun’s core; Nuclear Fusion occurs when trillions of atoms join, releasing energy. In the whole world around 1% of the world’s energy is solar power. Disadvantage of solar energy is how much it tends to cost and it requires space. Advantage it’s a renewable source of energy, its environmentally friendly and it requires low maintenance.

Biomass:

Biomass is fuel that is developed from organic materials, and it is a renewable and sustainable source of energy used to create electricity or other forms of power. Biomass is a renewable source of fuel to produce energy because waste reduces will always exist. It is a key building block of bio fuels meaning it can be grown for electricity production or to produce heat, as an alternative to fossil fuels. When burned, the energy in biomass is released as heat. (ex. wood burning in a fire place). 10% worldwide

Examples: scrap lumber, forest debris, certain crops, manure

forest debris manure scrap lumber

Biogas:

Biogas is produced through the breakdown of organic matter in the absence of oxygen. 6% worldwide

"The whole process works like a stomach would: Organic materials like manure, food scraps, crop residue, or wastewater sludgeare fed into the digester, where it’s heated to 38-40 degrees Celsius (temperature of a cow’s stomach) and stirred for 30-60 days, slowly producing a combination of methane, carbon dioxide and other gases (known as biogas)."

It is normally "underground"

Hydroelectric Power

Comes from the power of water. Uses a dam to hold water and then when it’s released it spins turbines creating energy . 16% of the world’s power resources are from Hydroelectric power. Disadvantage of Hydroelectric power is its environmental influence, It disrupts water flow, and many fish are caught in turbines, Advantage is that it doesn’t pollute like coal, oil, and other fossil fuels

Wind Power

Comes from the spinning of the turbines from wind. which actually is a result of hot air rising and cool air moving in its place. 1. 9% of the world’s energy is wind energy . Advantage it’s more environment friendly than fossil fuels . Disadvantage wind turbines can be threatening to wildlife and it’s very noisy

Solar power is the conversion of sunlight into electricity using concentrated solar power.

Concentrated solar power systems use lenses or mirrors and tracking systems to focus a large area of sunlight. Photovoltaic cells are cells that convert light into an electric current using the photovoltaic effect: it’s the creation of voltage or electric current in a material upon exposure to light.

Comes from the power of the sun.

Deep inside the sun’s core; Nuclear Fusion occurs when trillions of atoms join, releasing energy

In the whole world around 1% of the world’s energy is solar power

Disadvantage of solar energy is how much it tends to cost and it requires space

Advantage it’s a renewable source of energy, it’s environmentally friendly and it requires low maintenance.

Most solar panels will last up to 25 years.

China is the greatest world’s solar power producer

The history of solar energy in 1839, Alexandre Edmond Becquerel discovered that certain materials produced small amounts of electric current when exposed to light.

Top countries: Germany and Ital

Lowest countries: Latvia and Ireland

Beneifts: Solar power helps to slow/stop global warming, it is not only sustainable, but it;s renewable, never run out of it, silent producer of energy

Future: This study considers only the two widely recognized classes of technologies for converting solar energy into electricity — photovoltaics (PV) and concentrated solar power (CSP) or solar thermal.

Solar technologies have evolved a lot since they first made their debut in the 1960s. While previously solar photovoltaics (PV) were seen as a thing of the future, today, technological breakthroughs have positioned the industry for huge growth.

A series of new developments in solar technology also promise to contribute to the industry's success.

Our opinion towards solar energy and its various benefits about it, we think that it is a great source for long lasting energy and a environmental friendly one. We feel that it would be a worthy investment, since it give long lasting source of energy, slows global warming, and reduces fossil fuels.
