Renewable and Non-renewable energy sources
Biofuel - AJ
Advantages: Biofuels are relatively energy efficient, reduces our dependency on harmful non renewable oil, lessen air pollution, positively affect econ, sustainable, accessible, etc.
Disadvantages: Currently high costs, use of fertilizers, famine or shortage of food, industrial pollution, water usage, changes in land use, etc.
Definition: Biofuel is a type of renewable energy that is derived from the potential chemical energy stored biomass (organisms).
definition2
Examples: Wood, biogas, biodiesel, ethanol, methanol, butanol, etc.
Uses: Some uses of biofuel could be that biofuel is used for transportation fuels, thermal generation, electrical generation, etc.
Discovery: "Rudolf Diesel envisioned vegetable oil as a fuel source for his newly invented engine. The process the initiative uses to produce biodiesel was discovered in 1937." according to the University of Kansas.
COMPARISON: Compared to that of Nuclear energy, biofuel is believed to be safer and cleaner compared to the non-renewable resource of energy, nuclear energy. Biodiesel is a lot more affordable and accessible compared to nuclear energy, the possibilities and the costs of a malfunction may contribute to the limited accessibility of nuclear energy.
Ocean energy - sissi
Uses: Electricity generation, water desalination, heating and cooling, aquaculture, environmental monitoring
Advantages: renewable, clean source of energy, only requiring water's natural movement to generate power, abundant
Disadvantages: noise and visual pollution, costs of production, scalability issues, low performance in unfavourable weather
Definition: a form of concentrated solar energy that is transferred through complex wind-wave interactions
Examples: wave energy converts, tidal energy converts, ocean thermal energy
solar - Yushin
Disadvantage- High initial cost
Definition- Solar energy is any type of energy generated by the sun
Advantage- Solar energy is clean. It creates no carbon emissions or other heat-trapping “greenhouse” gases
Uses- Solar photovoltaics for electricity, passive solar design for space heating and cooling, and solar water heating
Example- Solar electricity, solar water heating, solar heating, solar ventilation and solar lighting
Geothermal Energy-lulu
Definition: Geothermal energy is heat energy from the earth, or the Earth's core. Geothermal energy comes from heat generated during the orignial formation of planet.
Advantage: It is always avaliable, silence energy, doesn't require large spaces, and safe and reliable.
Example: can be released through geysers, hot springs, steam vents,
Disadvantage: Possibility of deplation of geothermal sources
high investment cost
land requirement
environmental concern
Wind Power - Ethan
Definition: power obtained by harnessing the energy of wind.
Advantage: Clean and renewable, wind is an abundant and inexhaustible resource, also provides electricity without burning any fuel or polluting the air.
Examples: 1: Land-Based Wind Energy.
2: Distributed Wind Energy
3: Offshore Wind Energy.
Disadvantage: initial cost and technology immaturity.
Light Energy-Carrie
Disadvantage: Light energy is not always available, also, it is expensive to install and maintain.
Example: Flashlight, light candles, sunlight, bonfire, laser.
Definition: Light energy is a kind of kinetic energy with the ability to make types of light visible to human eyes.
Advantage: It is a clean and renewable resource. Sunlight itself is clean and non-polluting.
Coal - Jane
Definition- Coal is a black or brownish-black sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion
Advantage - Coal can be easily transported to the power stations. Coal is a relatively cheap energy source.
Disadvantage - Coal emit fly ash particles into the atmosphere, which contribute to air pollution problems. Upon burning, coal produces a number of gaseous byproducts, contribute to global climate change
Uses - Cement production, carbon fibers and foams, medicines, tars, synthetic petroleum-based fuels, and home and commercial heating.
Example - lignite, subbituminous, bituminous, and anthracite
Coal- Jessy
Definition : Coal energy is energy made by heat that is produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 1700s, English found out energy of coal
Advantage :Relatively easy and cheap to find and utilize
Disadvantage:Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, global warming, and other severe environmental and public health impacts.
Uses: Generate electricity, chemical production, and Gasification and Liquefaction
Thermal energy Memphis
Natural gas- Anna
Definition: Natural gas is a mixture of gases which are rich in hydrocarbons. All these gases (methane, nitrogen, carbon dioxide etc) are naturally found in atmosphere. Natural gas reserves are deep inside the earth near other solid & liquid hydrocarbons beds like coal and crude oil.
Advetange: easier to store and transport than other fossil fuels and renewables, it has one big storage disadvantage.
Disadvantage: Its volume happens to be four times as big as petrol's. Because of this, natural gas storage is much more expensive since more storage space is needed.
10 examples of Natural Gas: Water, ethane, butane, propane, pentanes, hydrogen sulphide, carbon dioxide, water vapor, and occasionally helium and nitrogen.
Thermal Energy Memphis
Advantages:Cost of power generation is cost-effective, Cost of power generation is cost-effective
Examples:The warmth from the sun, heat of a heater, etc
Disadvantages: Requirement of huge quantity of water
link to disadvantages: The use of fossil fuels cause depletion of resources
Definitions:Thermal energy refers to the energy contained within a system that is responsible for its temperature.
Nuclear energy by Heiyuen and Eva
Non-renewable and Renewable: nuclear energy is not renewable. But in terms of climate change, nuclear energy production does not release greenhouse gases, so it is a low-carbon fuel.
Examples: Electricity, Nuclear medicine, Food treatments
Advantage or Disadvantage pro: Small land footprint, High power output, Reliable energy source
cons: Very high upfront costs, Nuclear waste, Malfunctions can be catastrophic
Nuclear energy used: Not only in the creation of power and weapons, but also for medicine, space exploration and more.
Definition
a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons.
Compare with the Biofuel energy: Nuclear energy and Biofuel both have very high costs and can cause pollution.
oil sabrina
definition: produced when ancient remaiins of organisms (fossils) is refined into petroleum and combusted in oil fired power plant.
disadvantages: environmental pollutiion, nonrenewable, dangerous extraction process.
advantages: abundant uses, high energy density: 41MJ/kg, easy to store and transport, able to supply constant energy use.
other usages: oil products includes- gasoline, distalliates, such as diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oil and asphalts.
