Hey, can you please help me draw an isocost diagram to model a change in relative prices that would incentivise a shift in technologies? And also please help me calculate the innovation rent that arises due to this switch in technologies.

Moving a nation's source of power from fossil fuels (such as coal) to clean energy sources (such as solar) can reduce carbon emissions. Suppose the price of a unit of coal (Pc) is $50 and the price a unit of solar (Ps) is $30. A representative power plant can use a mixture of coal and solar inputs to produce one unit of electricity. The power plant has two types of technologies available to them to produce one unit of electricity: Coal (C) Solar (S) Technology A 10 units 2 units Technology B 3 units 20 units Assume that the power plant uses no other inputs in its production process
