A village is being built in the Netherlands that will be completely self-sufficient - from electricity production to food supply. The Utopia website shows what it will look like:

Contrary to the agreements in the coalition agreement, the draft budget presented by the Federal Minister of Finance, Olaf Scholz, on 2 May 2018 does not include tax incentives for the energy-efficient refurbishment of buildings. Deutsche Umwelthilfe (DUH) considers this a worrying revelation. The environmental and consumer protection organisation calls on the federal government to immediately launch a programme for tax incentives for the energy-efficient refurbishment of buildings and to increase the refurbishment rate for existing buildings from the current 0.8 percent to at least 2 percent per year.
"If the Federal Minister of Finance does not anchor this measure, which was agreed in the coalition agreement and is central to climate protection, in his draft budget, then he shows that he has either forgotten or already abandoned the climate policy promises of the new government after only a few weeks in office.", says Sascha Müller-Kraenner, Federal Executive Director of DUH.
Energy-efficient building refurbishment is a central element of the energy transition and climate protection. However, climate protection in the building sector will only be successful if the renovation rate in the building stock increases from the current 0.8 percent to over 2 percent annually.
"The two previous governments already failed to set the course for tax incentives in time and thus make a decisive contribution to achieving the 2020 climate protection target"Müller-Kraenner continues. "The reservations of the Länder that tax incentives would create a budget gap for them have been known for a long time. It is time to bring acceptable counter-financing solutions to the table."
After all, tax incentives for refurbishment costs are an important incentive not only for large housing associations but also for private homeowners to invest their own funds. The starting signal for this must now be given urgently.

URBAN MINING - The city as an eternal source of raw materials

45 min. A 2012 Broadcast from 29.10.2012. 3sat
While the mountains of waste in our cities are growing, raw materials are becoming increasingly scarce and expensive worldwide. For decades, mineral resources have been shipped to the industrial nations and used in high-rise buildings, mobile phones and cars, for example. Today, metropolises are gigantic raw material mines. Researchers and companies are now starting to mine.

BN - Is the roof of my house or company building suitable for a photovoltaic system or a solar thermal system? This question can now be answered quickly and conveniently online with the help of the new solar roof cadastre of the city of Bonn. In a building-specific map display, a coloured marker indicates whether and to what extent a roof is suitable for energy generation by means of solar power. Step by step, further information, for example on the economic efficiency, can be retrieved via a yield calculator.
The suitability of the roofs of all 129,000 buildings in the city for solar energy generation was recalculated using the latest, improved data. For this purpose, elevation grid data was used, which was determined by the district government of Cologne by means of laser scanning in spring 2016. Compared to the previous version from 2010, the new Bonn solar roof cadastre features, among other things, a fourfold higher resolution and a more differentiated designation of the roof areas.
The suitability of the roof surfaces for electricity generation via photovoltaic systems as well as for domestic water heating and, for the first time, also for supporting building heating via solar thermal collectors was calculated. The calculations also took into account the current changes in the framework conditions with regard to feed-in tariffs and self-consumption of generated solar power.
How the application works
In the city map, the installable system size and many additional data such as yields and savings potentials can be displayed for each building. In a newly developed yield calculator, costs and yields can be calculated and compared by entering additional user-specific information such as electricity consumption or household size. In this way, every owner can quickly gain an overview of the suitability of his or her building for the use of solar energy. Detailed instructions are available at www.bonn.de/...solardachkataster.php.
The City of Bonn points out that the information from the solar roof cadastre is an initial non-binding assessment. Essential prerequisites for a decision to build a system, such as the condition of the roof or the static suitability, can only be clarified by suitable specialist companies or qualified consulting organisations. Information on this can be found on the website of the solar roof register.
Bonn roofs have potential
According to the potential analysis of the solar roof cadastre, 6,800,000 square metres in Bonn are suitable for solar power generation. This corresponds to about the size of 950 football fields. Approximately 800,000 megawatt hours of electricity could be generated on this area. This could cover about 50 percent of the total electricity consumption in Bonn. For solar thermal energy, the result of the potential analysis shows 88,461 buildings in Bonn that could be used for this form of energy generation. This corresponds to about 70 percent of the buildings in Bonn.

In 2018, Deutsche Bahn fed 57 percent green electricity into the grid. This is an increase of 13 percent in electricity from renewable energies compared to the previous year. DB is thus already the largest consumer of green electricity in Germany.
