Simply, the substantial solution would be sunlight: http://www.asrc.cestm.albany.edu/perez/

For example, Concentrating Solar Power (CSP), Concentrating Photovoltaics (CPV), Customer Site Photovoltaics (CSPV) technology, ... centralized and at the point of use respectively. Comparison of the cost of construction a non-renewable resource with replenishment costs and the construction renewable resource with the source of 'exergy' as sunlight. And in the internal rate of return (IRR) and net present value (NPV) - include the many risk coefficients. Risk, if CO2 sequestration and (Green House Gas) GHGs were released inadvertently.

Remember the GHG is now > 380ppm ?: http://www.earthregenerationsociety.org/

For instance, instrumentation is available where one may measures and reports CO2 in the atmosphere. Sunlight is reliable, does not malfunction and would be predictable and works - specifically utility interactive for the short-haul, and for the 'long-haul'.

CSPVs are completed, implemented, proven and likely substantially successful with the observed number completed systems at approximately an average of ~ 4kW.” - for each person at the point of use distributed generation, but also centralized. If use of sunlight, then varies in size & technology:

Plan design, implementation and support proven working technology not only energy conservation (EC) energy efficiency (EE), but also Renewable Energy (RE):

• Active and passive solar power technology
• Solar inverter and monitoring technology
• Development and deployment of non rare earth materials for solar modules and solar collector technology and for the balance of systems (BOS), balance of plant (BOP), …
