Energy resources
Renewable
Water
Energy:
The energy gained by water is from harnessing the potential energy, transforming it into kinetic energy and using it to spin turbines, thus making electricity.
Drawbacks:
Limited number of locations, environmental impacts, high cost and matinance requirements.
Wind
Energy:
Wind has kinetic energy, and that is harnessed and used to spin turbines.
Drawbacks:
Expensive, wear out quickly
Inefficient, wind does not blow 24/7
Solar
Use:
Solar energy is used to power homes, stop signs, and even car charging stations. With an uptick in solar use in recent years, they are even being used to power universities, and even the international space station.

Energy:
Energy from the Sun comes from the lightest element, hydrogen, fusing together to create the second lightest element, helium. Nuclear fusion releases tremendous amounts of solar energy. The energy travels to the Earth as light. The light carries the energy through the empty space between the Sun and the Earth as radiation.
Geothermal
Energy:
Water is heated by hot rock under the surface and then pumped back to the surface for use. The hot water or steam from a geothermal well spins a turbine to make electricity.
Biomass
Energy:
Biodegradable wastes are used to create natural gas, which can then be burned

Non renewable
Non renewable energies are things that take a long time to replenish, essentially things that get used faster than they are made
What is it
Energy is essentially electricity; what we need for our every day life. It powers utilities, cars, batteries, ect.
Connections
Step 3
Dams cause sediment buildup, which can be an issue overtime requiring dredging.
Geothermal energy is most common along subduction and divergent zones. This is due to weakened points in the crust which allows for melt.
Step 4
One part of being an engineer is finding new ways to harness energy. For example, finding new ways to use solar energy more efficiently.
Global warming is significant to everyone's personal life, including mine. It is important that we work to reverse it so that I can enjoy the snow we get once every 10 years
Step 2
Renewable energy sources all have a main flaw: effieciency. They cannot work 24/7, nor is there a way to reliably store energy.
Almost all energy sources utilize turbines, such as wind turbines, nuclear producing steam to turn turbines, and water spinning turbines.
All fossil fuels are very limited, meaning that they take an extremely long time to form.
Non Renewable
Fossil fuels
Oil
Energy
Oil is used to produce fuels, is burned for energy, and is refined to make plastics.
Drawbacks
It is limited, meaning it has to be purchased from other nations in order to meet demands.
Natural gas
-
Drawbacks
While it burns cleaner than others, it still produces CO2. It is also limited, and will run out eventually.
Coal
Drawbacks
Coal produces ash and CO2 when burned, polluting the air and environment.
Energy
Coal is very abundant, and is burned in plants to gain energy from it.
Nuclear
Use
Nuclear power plants use various radioactive, most commonly thorium and uranium, elements to generate immense heat, which then boils water and turns turbines, creating electricity.
Energy
When the nucleus of an atom is split, it releases a huge amount of energy called nuclear energy.
Drawbacks
Accidents do happen, with meltdowns being particularly catastrophic. There are also biproducts with very long half-lifes, meaning they will not degrade for a long time.
