A system of tubes
Photons
This is
a flat solar panel
a photovoltaic panel

What is Solar Power?
The generation of electricity from the heat of the Sun
It is when you take the Sun and convert it into electricity
It is you UwU
It is the conversion of energy from sunlight to electricity
Which of the following are used to generate electricity from sunlight/solar thermal energy
Photovoltaic Cells
Radioisotope thermoelectric generator
Moving bed biofilm reactor
Compact linear Fresnel reflector
Catalytic converter
How does a Photo-voltaic Cell work?
First, light is absorbed and knocks electrons loose. The loose electrons then flow, therefore creating a current. This current is captured and transferred to wires
First, the PV Cell absorbs sunlight. Later, the energy from the sunlight is then converted into electricity by a Peltier inside the PV Cell. Wires then transfer the electricity into things that need power
Sunlight is intercepted by PV cells. It then grows barbaric and destroys atoms inside the PV Cell. The scared electrons then run away and get picked up by wires. The wires then resettle them in safe havens that needed free electrons
In 2017, the cumulative energy generated by solar power was?
Umm... 389 GWh
It's well over 460 TWh
Maybe 550 Kg
I don't know what else to write
What kind of solar power plant is this?
Just a regular Solar Power Plant
Dish Stirling-type Solar Power Plant
Solar Thermal Power Plant
Shiny Space Mirror to lighten up the surrounding area
What are the advantages of phasing into a solar-based electricity generation?
Solar power is pollution free and causes no greenhouse gases to be emitted after installation
Can be installed virtually anywhere; in a field to on a building
Virtually no maintenance as solar panels last over 30 years
Reduced dependence on nonrenewable sources and fossil fuels
Creates jobs by employing solar panel manufacturers, solar installers, etc. and in turn helps the economy
What are the disadvantages of solar power?
Needs lots of space as efficiency is not 100% yet
Oil is renewable so we don't need solar power
Useless because oil is much cheaper and easier to build than solar power plant
No solar power at night so there is a need for a large battery bank
It lacks you UwU
Do we need to ditch oil and embrace solar power?
Well, yes. You see, it is us who can't tolerate climate change. Nature can just do its thing and adapt. But, we humans are built to survive in this kind of environment with this kind of climate. So, in the end, it is us that will presumably perish. Plus, we can use the remaining fossil fuels to deter the next ice age that is due to happen in about 10.00 years
I'm biased, so you guys need to answer yes
No! Climate change is a hoax and we're all fine with fossil fuels
