Renewable energy (RE) plays an increasingly important role in the economy of almost every country in the world. In order to examine the state of renewable energy (RE) in Mazowieckie Voivodeship (Poland), a literature review was carried out, anonymous surveys were conducted, a SWOT (Strenghts, Weaknesses, Opportunities, Threats) and TOWS analysis were carried out and the potential of RE in Mazowieckie voivodship was estimated. The total capacity of all installations is equal to 712 MW. In recent months, number of prosumers have increased to 11,742 in the Voivodeship, and the capacity of their installations is estimated at 66 MW. Simplification of legal regulations and educating society is strongly recommended. Respondents in the survey and SWOT analysis on the future of the energy sector in Mazowieckie Voivodeship show that solar energy (35.5% of respondents) and wind energy (24.5% of respondents) have the greatest chances for the development. Development of the RE sector in the Voivodeship means new jobs, both in this sector and around it. Significant RE potential together with large project financing possibilities may cause Mazowieckie Voivodeship to be a leader in RE production in Poland. It is this Voivodeship (with its capital Warsaw) that can serve as an example of the energy transformation towards 100% RE.

可再生能源（RE）在世界上几乎每个国家的经济中都扮演着越来越重要的角色。为了检查Mazowieckie省（波兰）中的可再生能源（RE）状况，进行了文献综述，进行了匿名调查，进行了SWOT（优势，劣势，机会，威胁）和TOWS分析，估计了RE在Mazowieckie省的潜力。所有装置的总容量等于712兆瓦。最近几个月，省级的生产者数量已增加到11,742，其装置的容量估计为66兆瓦。强烈建议简化法律法规和教育社会。在对Mazowieckie省能源部门的未来进行的调查和SWOT分析中，受访者表示太阳能（35。5％的受访者）和风能（24.5％的受访者）拥有最大的发展机会。省级可再生能源部门的发展意味着该部门及其周围地区都有新的工作机会。巨大的可再生能源潜力以及巨大的项目融资可能性可能会使Mazowieckie Voivodeship成为波兰可再生能源生产的领导者。正是这种省（省会华沙）可以作为能源向100％可再生能源转化的一个例子。
