Individuals can, of course, make small-scale personal changes but they are too small for global purposes.
Solar panels make a valuable contribution to renewable energy but are the province of the wealthy. Those struggling just to survive week to week would find the capital outlay of a solar array impossible to finance. Changes need to reflect their situation and central government - or state - subsidies may be needed to help them.
Here in the UK many homes are poorly insulated - cold in winter, hot when the sun occasionally shines. Heat pumps installations are amazingly spendy and most homes need considerable alterations and potentially large amounts of additional insulation. And that's for homes with enough outside space. Ground source heating is all-but ruled out for many, air-source the only option. Cooling systems are rare but could become necessary as global temperatures climb and exceptionally high temperatures can be expected. (Just look at BC and OR and their temperatures right now - that could be the UK, we're on the same latitude)
Solar arrays are very expensive now government subsidies have been withdrawn and the demands on the electrical grid from new-generation electric vehicles in all countries will find them failing.
It's a global situation and the issues can not be resolved in your neighborhood, your town or city, your county, your state, your country or your nation by themselves...... We all have to be involved, wherever we live.
