"Collaborative alternitives" (my term) -- keep grid and "conventional fossil" for we'll need that level of power and its source perhaps forever for industry.
Build solar, erect wind, develop more tidal turbines.
Single-system neighborhoods or even buildings could collect at least part of their power needs for DC battery bank storage. The wind blows everywhere it blows. Multiple small-scale turbines (or alternative "squirrel-cage" configuration blades) would collectively collect what one monstrous turbine does.
The more incentives to LED lighting the better. The less lighting the better. Do we really need to light a whole room evenly when we savor the lumen-ambience of a resaurant or bar with just focals and surrounding glows? Do we need daylight lumens so the used cars on the lots aren't ascared of the dark?
One of the major "alternatives" with which we can collaborate and resolve energy and pollution problems is to use less
Our standard of living, our mobility, our heating McMansions entire (including cathedral ceiling "great room" while occupying perhaps just den or kitchen or bedroom is squandry. We need an "alternative system" to "central heat". Especially an alternative to tank water heaters is called for. Can you imagine keeping a big pot of water hot on your stove all day so that once or twice you can have a cup of coffee or hot chocolate?
As for snow on solar panels, so many people could be paid something for their services for their food stamps and such -- and with carefully designed shovels, clear the snow from the (almost all) ground-level "farms". Yes, superfund sites unless reeking and spewing carcinogens might be better left like "seeping dogs" to lie under the arrays of solar collectors. But building walls as well as roofs, pavement surfaces, many sources that the sun shines upon could be interfaced with "collection" of that solar energy.
