100

Energy conversion process that captures sunlight to create electricity

What is solar energy?

100

The lightest element 

What is hydrogen? 

100

Engineers design this to carefully control fission

What is nuclear power plants?

100

Radioactive material that emits highly energetic particles and can be very extremely dangerous 

What is nuclear waste?

100

A large contribute to biogas production

What is human waste?

200

Plants store this as well as glucose 

What is chemical energy? 

200

Provides 10% of the energy in the US

What is nuclear fission?

200

An atom splits into tow releasing this during nuclear fission

What is energy?

200

The National Academy of Engineers in the US has declared this goals as one of the grand challenges of the 21st century

What is providing energy from fusion?

200

In Brazil, 4 out of every 5 cars produced have hybrid engines capable of burning these two things

What is ordinary gas and bio-ethanol?

300

Biomass energy relies on this directly or by processing it into fuel

What is burning biological matter like plants?

300

This turns a nuclear reactor into a heat source for a power plant 

What is fission?

300

This releases the same amount or even less of greenhouse gases than most renewable energy sources

What is nuclear power?

300

These are the major set backs of providing heat from fusion

What is intense amounts of heat and pressure?

300

Biomass fuels release this into the atmosphere similarly to fossil fuels 

What is carbon dioxide?

400

This amount of biomass energy is delivered by burning plant matter directly 

What is about half? 

400

The same energy-releasing process that occurs in the sun 

What is nuclear fusion?

400

This can lead to disasters like Chernobyl or Fukushima

What is fission becoming runaway process?

400

One major challenge of nuclear fusion is reaching this extremely high temperature, which mimics the sun 

What is 100 million degrees Celsius?

400

Humans use this much of all CO2 absorbing plant matter on Earth

What is 1/3?

500

Releases gas like methane that can be burned for fuel (two answers) 

What is manure decay and human waste?

500

An extremely hot gas made of ions or atoms with an electric charge 

What is plasma? 

500

The worlds biggest fusion plant 

What is IETR?

500

The element produced in a fusion reaction as a byproduct and is essential for maintaining the fusion process

What is energy?

500

This is another source of biomass that can be used 

Algae?
