Who is a Virtual Prosumer? Settlement Rules in 2025
Using a photovoltaic installation grants the user the status of a prosumer. However, the current provisions of the Renewable Energy Sources Act distinguish between different types of renewable energy prosumers. As of July 2, 2025, in addition to individual, tenant, and collective prosumers, the virtual prosumer model also comes into effect. Who exactly are these users of photovoltaic systems, and what sets them apart from a "regular" prosumer?
Central Energy Market Information System – A Change in the Energy Market. What Does the Introduction of CSIRE Mean?
As of July 1, 2025, the Central Energy Market Information System (CSIRE) is operational in Poland. Although its full implementation will take place in a year’s time, we can already see whether the centralized transmission, storage, and sharing of electricity market data is actually working. What exactly is CSIRE, and how does it function?
Green Marketing for Companies – How to Implement It?
Environmental protection, conscious care for preserving its values and biodiversity, promoting pro-environmental attitudes, and optimizing business activities are the key principles of green marketing. When companies define areas for development and create strategic and operational plans, their implementation can help eliminate the destructive impact on the planet. At this stage, questions and doubts often arise - What exactly is green marketing?
What is the deposit return system and from when will it be in force in Poland
The deposit return system is a solution introduced in response to the provisions of the Single-Use Plastics Directive, also known as the plastics directive. Its aim is to increase the level of recycling and to reduce the amount of waste ending up in the environment. In Poland, it will come into force in October 2025, although it was originally planned to be launched much earlier. What is the deposit return system, and how has it worked in other European countries?
Wind turbines — how do they work and what should you know about them?
Renewable energy sources are not limited to photovoltaics or hydroelectric power. In areas with strong winds, it is also possible to harness their potential to generate electricity. Here, we take a closer look at wind turbines—both large-scale industrial installations and smaller household solutions. How do they work, and is wind power a cost-effective source of energy?
What is greenwashing? Examples of the phenomenon
Today, being “eco-friendly” is a global trend that more and more companies are following. Many do so in good faith, with the genuine intention of benefiting the environment. However, there are also companies that, under the guise of implementing ecological initiatives, hide actions that have nothing to do with sustainability. Such unethical practices are known as greenwashing. Read on to learn how to recognize greenwashing and how to counteract it — what is it really?
How to save electricity every day? Saving electricity at home
Between 1999 and 2022, electricity prices for households increased by nearly 190%, and costs continue to rise. Although the government has introduced various protective measures in recent years, many families still pay a high share of their income for electricity. So how can you save electricity on a daily basis to relieve your household budget in a meaningful way?
Green building certifications overview: LEED, BREEAM, WELL and other
In the mid-1980s, media attention focused on tragedies such as the Chernobyl nuclear explosion, the Bophal disaster in India, and the Exxon Valdez spill. As economic development increasingly interfered with the environment, people began to look for ways to make building structures safer. This is how the concept of Green Building was born. What certifications can companies planning infrastructure apply for today, and why invest in green building?
What Is a Passive House? Key Principles and Benefits
Passive houses are a symbol of a sustainable approach to construction, considering both human and environmental needs. Thanks to low energy demand and high user comfort, they are gaining increasing recognition worldwide. What exactly is a passive house? What design principles must be followed? What technologies are used in this type of construction? What role does renewable energy play in these buildings? And most importantly—what benefits come from choosing a passive house?
Energy efficiency of heat pumps - what is worth knowing?
Heat pumps are, next to photovoltaics, one of the most popular technologies using renewable energy sources. By transferring thermal energy from the so-called “bottom source” - the ground, air or a body of water - it is possible to heat a building at a much lower cost than using classic CO. However, the energy efficiency of a heat pump can vary depending on a whole range of factors. What affects the efficiency of a heat pump and can this parameter be improved?
Carbon Credits – What Is Their Role in Combating Climate Change?
Mitigating and preventing climate change are goals that require decisive and large-scale action. One of the key elements of the global strategy to reduce greenhouse gas emissions is the Carbon Credit system. It serves as an incentive mechanism that promotes the use of renewable energy and reduces the negative environmental impact of businesses.
