Increasing the share of renewables would directly lower the average cost of electricity production, and has the potential to reduce wholesale prices in the long term. [...] The share of renewables increased to 24% in the first half of 2022, mainly due to an increase in the share of wind power (from 10% to 14%), and an increase in the share of solar power (from 2.3% to 3.9%) compared to 2021 (EEA, 2022). [...] While Poland’s wholesale prices have been relatively stable among the highest in Europe in the last decade, in late 2021, Polish wholesale and low in the prices did not increase as dramatically as in neighbouring countries such as last decade Germany, the Czech Republic and Slovakia, and were among the lowest in Europe at the end of 2021. [...] Even though the average monthly change of electricity, gas and ‘fuels and lubricants for transport’ (petrol, diesel and motor oils) is similar in the period 1995-2021, the standard deviation (an indicator of volatility) of diesel and petrol is by far the highest, while electricity and gas are not as far from each other, with the volatility of gas slightly lower. [...] Retail energy prices are a component of the consumer prices index of the recent (CPI), and their weights account for around 10% of the overall basket of goods consumer price and services included in the CPI (gas and fuels account for around 7% and inflation electricity for around 3%).
