The graph illustrates the proportion of homes using electricity and natural gas for heating, categorized by the period in which the houses were built.
Overall, homes built more recently tend to rely more on electricity, while natural gas was far more popular in older houses. Electricity use shows a steady upward trend, whereas natural gas steadily declines.
For houses constructed before 1950, natural gas was the dominant heating fuel, used in about 60% of homes, compared to only around 15% that relied on electricity. A similar pattern is seen in homes built between 1950 and 1969, where natural gas remained at approximately 60%, while electricity increased slightly to about 25%.
