The  Paris climate change pact , which  entered into force  last year, was announced with a huge fanfare. The deal aims to limit the rise in average global temperatures to “well below” two degrees Celsius, compared to pre-industrial levels.

Where’s the best place to set up a factory in Europe? Athens , of course! As unexpected as it may seem, the Greek capital ranks first in a special list of 40 regions across the EU , for conditions ideal for the integration of renewable energy, notably solar, in manufacturing activities .

Renewable energy crowdfunding involves three different parties: the fundraising platform, the investors  who generally expect a return, and project developers needing money. They may come from different nations .

Part of the issue with small-scale, home-based renewable energy systems is that initial setup costs can be high. This puts such installations out of reach for some sectors of society, even if they could benefit financial in the long run with lower household bills.

The energy landscape in Europe is changing rapidly and the percentage of renewables is steadily increasing. For example, in Germany solar and wind power provided an average of 33% of the total electricity production in 2015.

Suburbs are often spaces of poverty, unemployment and urban decay. But now many peripheral areas are becoming laboratories of innovation , hosting initiatives for a sustainable future.

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”).

It's a brand new sector: the first steps date back to 2012. Today energy crowdfunding is a way of financing solar panel or wind turbine projects.

Turkey has started considering its own sources to generate electricity as a way to make it less  dependent on fossil fuels, which account for 90% of the country’s current energy supply.

In the late 1980s, the German-born chemist Michael Grätzel literally tied his name to an invention that is hailed as a  revolution in renewable energy .

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.

Traditionally our electricity grids were designed to move power from large nuclear and fossil fuel power plants to consumers, but renewable energy will see changes to allow smaller power generation from wind and solar to be hooked up to the grid.

Innovative technologies can be used to retrofit old buildings as a means to save energy. This is precisely what the Bricker project is aiming to achieve.

Retrofitting existing buildings with adequate cutting-edge technologies is thought to guarantees spectacular energy savings, by about 50%. The objective of the EU funded project BRICKER is precisely to demonstrate such possibility.

Retroffiting older buildings has become an industry in its own right in Europe. To compete, various players need to innovate.

There is nothing like the real world to reveal a project’s true worth. This is why a project called BRICKER will test its mettle out by retrofitting public buildings situated in three different countries in three different climatic zones .

Innovative solutions are required to improve the energy efficiency of the existing residential building stock in Europe. But combining such innovation with better management and new business models creates unique retrofitting opportunities .

To prevent energy loss and improve the management of solar power plants scientists of the European research project MACC II in France are now developing a 5-day forecast to predict the movements of desert dust and thus will be able to inform power plant managers beforehand.

The heating and cooling of buildings take a large share in the energy consumption in Europe . The average energy consumption in the non-residential sector, such as public and industrial buildings, is estimated to be at least 40% greater than in the residential sector.

Renewable energy sources play an important role in securing future energy supply and mitigating climate change.
