It depends on how you account for mitigating factors. With wind production, the wind turbines take up more space than other power sources. However, off-shore wind turbines negate that space requirement, so if a region can do that it is better than taking up land for energy production. With solar production, the solar panels take up more space than other power sources. However, it is common to place the panels on building roofs where no additional space is taken up. There are even places like France that make use of solar panels on the roofs of other building types like bus shelters and car parks. Done this way, solar does not need any additional/dedicated space. I've also seen small wind turbine/windmill blades on road signs along with a small solar panel in Wales that don't take up any additional space. These also have the advantage of being self-contained so you don't need to have cables connecting them to the power grid.
