This article mathematically accurately reveals the reasons for the phenomenon of the acceleration of the growth of the greenhouse effect in response to the increase in financing of renewable energy sources. Schemes for replacing traditional energy sources with renewable ones are accompanied by calculations. Recommendations for overcoming the phenomenon are given. Each reader has the opportunity to check the proposed solutions with simple calculations.

Thank you Valery , I'm glad it was such simple calculations to determine how each area should proceed. It seems each area should look at how they are using the Renewable sources they already have. I live in Arizona  and we have about 10% of our power from Hydro. The dams were all built about 50 years ago. They were made for flood control since we don't get much rain but when we do it comes in torrents and floods. 

   I have been working to get them all upgraded as new equipment can let them produce twice as much power. I have got them to at least upgrade when they do repairs and maintenance . 

    In other areas I'm sure they haven't made the most of their resources. Geo-Thermal for one is often over looked. Wind and solar are finally starting to grow like they should but they could be placed to provide needed shade as well as make power. Battery storage should also be part of the design. 

    What resources do you see not being used to their best advantage ?

Thanks Jim for your question. It showed that we have reduced the volume of the article excessively. The essence of our method is to individually ensure the energy efficiency of any changes in the power system. For example, if you have a long-built hydroelectric power plant that produces G1 of energy, then its age is not a reason for its mandatory modernization. Modernization has an energetic sense if the energy cost Lm for it will be less than the increase in energy generation after its completion. That is, the energy generation after the modernization of G2 must be greater than G1 + Lm. But the energy costs for the modernization Lm must be calculated in a special way - according to the principle of calculating the energy costs for the life cycle of this modernization. These costs are now very rarely calculated In this way in scientific research. For example, such calculations are made by NREL. And we propose to calculate them in this way always.

This method of calculation is similar to calculating the cost of money for modernization Cm. Economically, modernization makes sense if the cost of money for it Сm will be less than the increase in money receipts from consumers М2 after its completion. That is, the income after the modernization of M2 must be greater than M1 + Cm. Any cost of money is always calculated for the entire life cycle and there are no problems for such calculations. Any costs of money are always calculated for the entire past period of the life cycle and there are no problems for such calculations. Money calculations are automated. Energy costs can be calculated in a similar way.

Consequently, the IEA must perform for any resource the calculations, according to our methodology in order to answer your second question about its effective use. The IEA calculates only economic efficiency today.
