We already have smart power monitoring and power management systems. All power stations can be transformed to hybrid. We can program to use solar energy, wind energy, tidal energy, Oil & gas etc. All available forms of energy can set on priority bases according to availability. We may not need electric cars for now but electrical power production facilities can decrease significant emissions. We can not totally sweep out Oil and Gas as these are very affordable sources. Also we should not occupy land with solar panels, Solar power design should incorporate green houses or other useful production under the roofs of solar panels and walls designed for natural light. On remote places community grids can be designed with backup from other sources of energy when sunlight is not available.
