All three are terms that get to the same basic concept and could be used interchangeably for the most part.
The environmental benefits of choosing to use electricity over on-site fossil fuel combustion to power homes, transportation, businesses, and industry are increasing. Several factors are contributing to this trend: Greenhouse gas emission rates of grid-generated electricity are steadily decreasing; end-use efficiency of electrical appliances continues to improve; penetration of variable renewable electricity production on the grid is rising creating the need for flexible loads; and new electric technologies are available and are decreasing in price.
Many studies say that to achieve deep greenhouse gas reductions, increased electrification is required. A study by Lawrence Berkeley National Lab, for example, finds: The key to meeting GHG goals is “widespread electrification of passenger vehicles, building heating, and industry heating.”
