Different types of energy
Renewable energy sources
Hydropower
Wave and tidal energy
Windpower
Geothermal energy
Solar energy
Biomass energy
Called "Clean energy" or "green power" as it doesn't pollute the air or water
Made from resources that earth will replace like:wind, water and sunshine
Solar energy
-Any type of energy generated by the sun
-Created by nuclear fusion the takes place in the sun
-Is derived by capturing radiant energy from sunlight and converting it into heat, electricity or hot water
-The cleanest and most abundant renewable energy source
-Most common form of solar energy is harnessed by solar panels or photovoltaic cells
Cons
1.For personal homes homeowners also need to have the ample sunlight in space to arrange their solar panels
Pros
2.relying on solar power help us improve public health and environmental conditions.
1.Limitless supply of solar energy
3.in long term could eliminate energy costs
4.in short term could reduce your energy bills
Hydropower
-Uses the natural flow of moving water to generate electricity
-Hydropower generates power by using the elevation difference created by a dam or a diversion structure
Pros
1.Clean and cost-effective form of energy
2.Can provide power immediately
3.Very versatile and can be generated using both small and big projects
-Does not produce pollution
-Most commonly used renewable source of electricity
-Most hydroelectric power plants have a reservoir of water, a gate or valve to control how much water flows out of the reservoir and a place where water ends up after flowing downwards
Cons
1.Expensive
2.There are limited reservoirs
3.There are droughts
4.Use more energy than they are being able to produce for consumption
5.Storage system may need fossil fuel to pump water
6.Disrupts waterways and negatively impact animals living in them and cause change in water levels,currents and migration patterns for fish and other freshwater ecosystems
Hydropower plants are located near a water source
Wave and tidal energy
-Renewable energy powered by natural rise and fall of ocean tides and currents
-Tidal energy can be harnessed using underwater turbines similar to wind turbines
-Water flowing through the turbines turns the blades, which turns the generator producing electricity
Cons
1.The cost of installing and maintaining a large wave or tidal plant is expensive
2.There are limited number of locations where current technologies can be installed
3.Those who live in land locked states won't have access to this type of energy
4.Can disturb the ocean's ecosystems
5.Needs large machinery to be built nearby which could cause disruptions to the ocean floor and sealife
-Wave and tidal energy converters are located near the coastline as it is easier to install, maintain, capture,and retrieve the energy
2 types of energy produced:
1.Thermal energy
-Relies on warm water surface temperatures
2.Mechanical energy
-Use the flow of the tides to generate energy
Pros
1.Predictable and easy to estimate the amount of energy that will be produced
2.Energy is much more consistent
3.Abundant
4.Has high energy production potential
Biomass energy
-Energy generated or produced by living or once living organisms.
-The most common biomass materials used for energy are plants,wood and waste or also called biomass feedstocks.
-Can also be a nonrenewable energy source
-Biomass can be burned by thermal conversion(heating the biomass feedstock in order to burn or dehydrate) and used for energy.
Pros
1.Always widely available
2.Less garbage in landfills
3.Carbon-neutral
Cons
1.Requires a lot of space
2.Still releases greenhouse gases
3.Inefficent in terms of how much energy it takes to create electricity
4.Possible deforestation
5.High cost
Geothermal energy
-Heat produced deep in the Earth's core
-Geothermal power plants draw fluids from underground reservoirs to the surface to produce steam
Areas of geothermal energy are usually close to the boundaries of tectonic continental plates
-Comes from heat generated during the original formation of the planet and the radioactive decay of materials
Pros
2.Reliable source of power
3.Small land footprint
1.Has significant potential for energy supply
4.Naturally replenished therefore does not run the risk of depleting
Cons
1.High cost to build infrastructure
2.Location dependent as it is vulnerable to earthquakes
Wind power
-The use of wind turbines to generate electricity
-Wind turbines convert the kinetic energy in the wind into mechanical power which is then converted into electricity by a generator
Pros
1.Clean and renewable energy source
2.Low price energy source
3.Can open up new job opportunities as turbines on the farms needs to be maintained
Serveral form of systems used to convert wind energy
1.Commercial grade wind power generating systems
-Can power many organizations
2.Single wind turbines
-Used to help supplement pre-existing energy organisations
3.Utility scale wind farms
-Purchased by contractor wholesale
Cons
1.Since wind farms are built in rural areas they are far from bustling cities where electricity is needed most, electricity must been transported through transition lines leading to higher cost
2.Wind turbines dominate skylines and create loud noises
3.Also threaten local wildlife.For example ,birds are killed by striking the arms of the wind turbines
