Electric heaters may convert electricity fairly efficiently, but generating electricity itself is a fairly inefficient process. Overall, electric heaters will be less efficient than petroleum-fuel heaters. This is why most central home heating systems use natural gas or petroleum gas whenever they are available.
The Progressive Era was a period of widespread social activism and political reform across the United States, from the 1890s to 1920s. The main objective of the Progressive movement was eliminating corruption in government. The movement primarily targeted political machines and their bosses.By taking down these corrupt representatives in office a further means of direct democracy would be established.n the 1940s typically historians saw the Progressive Era as a prelude to the New Deal and dated it from 1901 (when Roosevelt became president) to the start of World War I in 1914 or 1917. Historians have moved back in time emphasizing the Progressive reformers at the municipal and state levels in the 1890s.
Beginning in the late 1800's and lasting through the early 1900's, the Progressive era was a period of reform. The reform movement hit nearly every sector of life; from political changes such as the 18th amendment which allowed women to vote to social changes such as the prohibition.
