Question

global sources of energy■ crude oil■ combustible renewables■ coal and coal products■ nuclear■ natural gas■ hydro, geothermal, solar, windmost sources of energy around the world come from☑ nonrenewable resources.this graph shows that the use of alternative sources of energy as a percentage of the total source of energyx is increasing greatlyis decreasing greatlyhas changed very littlee use of crude oile.

Explanation:

1. First, identify alternative energy sources from the legend: these are Combustible renewables, Nuclear, and Hydro, geothermal, solar, wind (the top three colored segments of the stacked area chart).
2. Observe the total height of these alternative energy segments from 1995 to 2010: their combined height grows from around 1 billion tons of oil equivalent to around 2 billion tons, while the total global energy use (full height of the chart) grows from ~8 to ~12 billion tons.
3. Calculate the percentage change: 1995 alternative share ≈ $\frac{1}{8} = 12.5\%$; 2010 alternative share ≈ $\frac{2}{12} ≈ 16.7\%$. This is a small change, so the percentage has changed very little.

Answer:

has changed very little
