ENERGY EFFICIENCY Flashcards
What is the best way to ensure investment flows towards low-carbon emitting plants?
Using electricity when the carbon intensity is low.
What is energy?
Energy is the ability to do work and can be in different forms such as heat, electrical, and chemical.
How is electricity produced?
Electricity is secondary energy converted from another energy type.
What consumes electricity in software?
All software, from mobile applications to data center operations.
What is one of the best ways to reduce electricity consumption in software?
Making applications more energy efficient.
What should green software practitioners focus on?
Taking responsibility for energy consumed by their products and designing them to consume as little as possible.
What is the final step in the energy efficiency chain?
Ensuring the end user of the product is not creating unnecessary emissions.
How can batching jobs help in energy efficiency?
By taking advantage of energy proportionality.
How is most electricity produced?
Through burning fossil fuels such as coal, oil, and natural gas.
What is a common misconception about electricity?
That it is clean because it doesn’t directly dirty our hands or require exhaust pipes for devices.
What is the single most significant cause of carbon emissions?
Energy supply from burning fossil fuels.
What should be our goal if we want to be carbon efficient?
To be energy efficient by using the least amount of energy possible per unit of work.
What are the types of low-carbon energy sources?
Clean energy, green energy, and renewable energy.
What is clean energy?
Energy that doesn’t produce carbon emissions, e.g., nuclear.
What is green energy?
Energy sourced from nature.
