Question

analyzing graphs of natural resource use
graph 2
energy consumption in the united states (1776 - 2019)
quadrillion british thermal units

1. since 1776, how has overall energy consumption changes in the us?
2. how is the overall amount of renewable energy changing?
3. why do you think the amount of coal has been decreasing? is there another source that may be taking its place?

Explanation:

1. By observing the graph, overall energy consumption in the US has generally increased from 1776 - 2019 with fluctuations. Different energy - sources have contributed to this growth at different times.
2. The overall amount of renewable energy, as shown in the graph, has been increasing over time, indicating a growing share in the energy mix.
3. The amount of coal has been decreasing likely due to environmental regulations, the rise of cleaner energy sources like natural gas and renewables, and the relative cost - effectiveness of other energy forms in some cases. Natural gas and renewables may be taking its place.

Answer:

1. Overall energy consumption has generally increased with fluctuations.
2. The overall amount of renewable energy is increasing.
3. Coal is decreasing due to environmental regulations and competition from cleaner and cost - effective sources like natural gas and renewables.
