Dynamics of Changes in Total Consumption of Most Important Renewable Energy Sources in Poland

The strategic goal of Poland’s energy policy is to take actions that will increase the share of energy from renewable sources in the final gross energy consumption to 15% in 2020 and 20% in 2030. The effects of these actions will be: a reduction in greenhouse gas emissions, improvement of the security of energy supply, the development of innovative sectors of the economy and an increase in employment in individual regions of the country. Based on the Central Statistical Office data, the most important renewable energy sources were analyzed. Their consumption in 2006–2016 was compiled in the global system for Poland. It was found that during this period the share of individual energy sources in the total consumption of renewable energy were respectively: 80.7% for solid biofuels, 8.2% for liquid biofuels, 5.3% for wind energy, 2.6% for hydropower, 2% for biogas and 1.2% for other renewable energy sources. In addition, the following indicators were determined in the article: the maximum relative changes in consumption, maximum changes in the share of consumption, as well as the periodic and annual rate of change in the consumption of these energy sources in Poland. The largest increase in energy consumption was noted for solid biofuels and wind energy, while the highest dynamics of change was determined for: wind energy, other renewable energy sources (biodegradable municipal waste and solar energy), as well as liquid biofuels and biogas.
