• They are more reliable

• They produce more energy

• They are easier to control

Why is wind energy often not fully utilized in Kansas?

• High production costs

• Low demand at night

• Lack of wind

• Technical issues

What is the primary challenge with integrating renewable energy into existing power grids?

• High costs

• Intermittency of energy sources

• Lack of technology

• Overproduction of energy

What is 'load flexibility'?

• A storage solution

• A renewable energy source

• A grid management technique

• A type of power plant

How are smart devices contributing to emissions reduction?

• By using less electricity

• By operating only on renewable energy

• By tapping into the grid at the cleanest times

• By storing excess energy

What percentage could emissions decrease by implementing smart technologies across the Texas power grid?

• About 20%

• Around 10%

• Up to 30%

• Nearly 15%

What could be the global impact of coordinated device usage on power grids?
