Social, green, but primarily as an investment: all the features of energy crowdfunding There are three ways a crowdfunding project can be financed. Lending: the entrepreneurs borrow money and pay interest; equity: investors in the project become its shareholders; donations: no reward is to be expected (there is a fourth way, a mix of equity and lending called “hybrid”).

Dressing the power lines to bring more renewables to the cities
Dressing the power lines to bring more renewables to the cities To date, European consumers pay more for energy from renewables than for energy from conventional resources. One of the reasons is still the immaturity of the technology used for harnessing and distributing renewable energy.
Can sustainable office buildings increase workers’ productivity?
Can sustainable office buildings increase workers’ productivity? Efforts to make buildings environmentally sustainable often focus on the technical side, such as energy efficiency. But there is more to sustainability than just energy efficiency.
