Your country has most likely real green electricity providers, as they purchase or implement the appropriate capacities of green electricity for each customer. The other electricity providers only offer an electricity mix. The share of green electricity is sold more expensively as an eco-tariff to some customers, while the other customers theoretically only receive the shares of gas, coal, etc. http://www.imodeler.info/ro?key=CF8Gsu47BnYHLi5NHUWXKVA

LED 'light bulbs' are now available for really all lamps, even with pleasantly warm light colors.

Streaming can hardly be stopped. It is convenient if all data is automatically backed up in the cloud and can be accessed from anywhere, and it is equally convenient if all shipments can be viewed not only at a certain time, but 'on demand'. It can also be argued that computers no longer need such large hard drives and CDs or BlueRays no longer need to be produced. In the end, however, streaming all over the world means a considerable energy demand and the infrastructures for transmission towers devour space and raw materials and they probably also cause harmful radiation. One solution is therefore to give up comfort a bit and perhaps also go more into nature instead of squatting in front of the screen. In detail, there is still the possibility to download something more at home with fiber optic, than on the go with older mobile networks.

We have to use all suitable areas for photovoltaics (PV), as the variants on open spaces restrict nature and agriculture. A trend is PV on stilts, so that it can still be gardened or cultivated underneath. But that costs building material. Photovoltaics has become amazingly inexpensive today thanks to cheap panels from China. Unfortunately, there is hardly any money to make from the feed into the power grid, currently about 8 cents per kWh in Germany. Therefore, PV should always be combined with its own electricity storage (own step, see below) so that as much electricity as possible is consumed by yourself. This then saves approx. 25 to 35 cents per kWh (depending on your tariff), which we would otherwise have to pay to the electricity provider. In this way, your own PV system, adapted to your own electricity consumption, pays off after just a few years. If you have a car, you should take into account its consumption (even if it is not yet an electric car). Then the savings are much bigger. The banks like to give loans for PV, quite often it is also being subsidized. In addition, there are also providers who take over the costs and virtually rent the roof area and offer discounted electricity in return. Such providers then form so-called virtual power plants with other houses and their batteries. For such a dependency, you should inform yourself well about what is best for you.

An electricity storage system primarily helps to maximize the yield of the PV system if the electricity is not fed into the grid for little money, but comes out of the battery in the evening and then allows the full electricity price to be saved. Another advantage may be that some batteries work as an island system in the event of a power outage. The already mentioned virtual power plants then access your battery from the outside and make the electricity available virtually in the neighborhood and compensate you for it. In addition, power grids are stabilized and even with little wind and no sun, we can consume renewable energies. Note on lithium: Like many other raw materials, lithium is often problematic during mining. However, the life cycle assessment must take into account that we can recycle lithium for hundreds of years. In the basement, older lithium batteries from the automotive industry could also come to a second life later or, alternatively, sodium batteries that require more space.

Modern lamps require little electricity, and yet it is worthwhile not to let them burn unnecessarily, for example when we are not in the room for a long time.

There are almost hostile prejudices against electric cars: child labor, coal power, risk of explosion, farmers are expropriated, fear of range, loss of value, etc. It is true: Like every car, electric cars are also a waste of raw materials and energy. But if car, then the electric car is the best solution, because gasoline and diesel perform even worse in all areas. Many studies or Statements by laymen make a mistake: The controversial lithium must not only be counted with its footprint from mining, but this must be reduced by the many times that lithium is recycled again and again in the decades. In addition, what few know: Gasoline contains almost the same amount of electrical energy on 100km for production and transport as it is needed in an electric car for the journey. E-cars would not have to be so expensive and batteries not so big - charging options are more important. Electricity at public charging stations is currently surprisingly expensive, although it would clearly be more important to add the costs of the climate catastrophe and air pollution to the gasoline and diesel price. http://www.imodeler.info/ro? key=Col-EWhyCbIR_KGGP7mXbLw Hydrogen and synthetic fuels in cars are nonsense. There are so-called memes fuelled by individual interests (keyword "Lex Porsche" https://www.cleanthinking.de/lex-porsche-lindner-wissing-e-fuels/), 'ego trolls', which are picked up by 'Troll-Lemmingen', who simply like to be against something and do not want to change. With both fuels, green electricity is first generated and then with loss of efficiency to hydrogen or e-fuel. For e-fuels, carbon is also missing - already today, few airlines that have started with it have a problem buying carbon on the market. Consideo has also gained important insights about hydrogen: https://www.consideo.com/files/consideo/pdfs/papers/eng/ConsideoPaper-BEM-Engl.pdf In companies, of course, electric cars are also associated with additional expenses. However, if the electricity itself is produced, the self-consumption of electricity can be maximized and the costs are even lower in the end.

A premium SUV can weigh well over 2.5 tons and consumes more than twice as economical vehicles. Van, buses are similar - but sometimes have an authorization, for example as then actually used 7-seaters or for regular transports. For rare transports, there should be rental cars nearby or trailers. There is a global trend towards SUVs. These unconsciously give us the feeling of robustness, of getting through. They reinforce the so-called attribution or distinction need. We think we are the great car. At the same time, however, the same applies: Small cars are not necessarily more economical than larger cars - a Renault ZOE apparently consumes more than a Tesla Model Y. But larger cars consume more raw materials in the end. There is the expression SUV shame when you behave selfishly recklessly towards future generations through SUVs, comparable to flight shame.

Especially older e-bikes have to be loaded more often and many shy away from the bicycle holiday because the bikes are no longer the newest. Hosts could set up a repair station here.

No question - leaving the car and taking the bike is a proud feeling and healthy. If you don't want to exhaust yourself - for example on the way to the restaurant or museum, you can consider an e-bike. If you have a lot to transport, a cargo bike. And if you shy away from bad weather, you will find great cycling clothing today, which completely refutes the argument. Hosts can actively advertise their offer here.

Consistently separating waste, including green waste, glass and paper, is not as self-evident as can be assumed. Many make little effort here and don't really know what belongs in which bin. The residual waste bin also costs the public sector a lot of money, while the recyclable and green waste bin are free of charge. But also special waste, such as batteries, incandescent lamps, electrical appliances, etc. must be disposed of properly. Hospitality businesses and events can place separating waste bins with information signs everywhere. In general, it is also possible that a sign indicates that the cleaners take over the separation for the guests. But better, the guests can do that.

Non-recycled paper is often cheaper, but means cutting of forests, contamination of water during production and a high energy requirement. Recycled paper for toilet paper, writing paper, packaging, envelopes, wrapping paper, etc. should be a matter of course today. But we have to pay attention to it and choose it. Recycled paper is also snow-white, but it should then not be bleached with chlorine but oxygen. A note on the menu can make you proud and contribute to corporate identity.

Saving paper helps to protect forests - recycling paper also ultimately means more demand for fresh pulp from trees. We don't even need to print many things in the first place, but can save them on devices that we already have. For internal processes but also for dialogue with customers, digital forms should continue to prevail. So the guests are welcome to ask if they need a paper version of the invoice.

After unpacked and for drinks after the tap water, the best thing we can do is to buy our food in reusable containers. (By the way, there are also reusable shipping boxes for office supplies as well as some regional delivery services). Also ask whether the containers are transported empty throughout Germany, or whether North German beer flows into the empty bottle of Bavarian beer and vice versa. Next question, what energy does it cost to clean the containers. Composite packaging or cans that are easy to recycle are the better alternative in some studies. In such studies, it is necessary to look closely at what is being compared. Ultimately, it is important to close regional cycles. Next question, whether the containers should be made of glass or plastic - glass is recycled more often, plastic is lighter and means less energy during transport.

Organic cleaning agents can be found in all supermarkets and drugstores. An essential feature is biodegradability and, of course, the vegetable raw materials as an alternative to petroleum-based raw materials. Even if conventional cleaning agents are classified as safe, organic cleaning agents are certainly safer and are less harmful to health and also burden the sewage treatment plants less.

Many furniture cannot stand being moved or even disassembled and reassembled. They are primarily cheap and the business model is that after a few years we want to buy new furniture. Looking at how valuable the furniture is and then being able to repair it takes us a whole lot further on the way to a better world. It is also amazing what good pieces there are on the used market.

Ecological furniture is made of natural materials without questionable chemical additives or varnishes. They are usually very expensive, but also last many decades and can usually be easily repaired and renovated.

Green IT starts with the devices and goes on to the power consumption from streaming to the use of IT to increase efficiency. The devices are about the use of used or refurbished devices, repairable devices, the recycling of materials and the minimization of questionable raw materials.

Many devices from vacuum cleaners to cordless screwdrivers to TVs are amazingly inexpensive today. Relying on valuable devices that last a long time, or even buying used devices, helps to save raw materials and energy.

Unfortunately, many devices can no longer be repaired at all, for example if the control unit breaks down from the washing machine and costs more than a new washing machine. And yet there are workshops that also repair mobile phones, washing machines, lawn mowers, etc. - and even if it is as expensive as a new device, it is the good feeling of having done something for a better world again.

Transparency in the supply chain should not only strive for the larger companies committed to doing so. This also includes the knowledge of the working conditions under which people work. Child labor and slavery are still common and inhuman working conditions and hunger wages are often at the beginning of the supply chain in the mines and factories abroad. Here, a company can exert pressure and remunerate better accordingly.

Especially at the beginning of the supply chains, there is a lot of environmental pollution but also land robbery (expropriation such as clearing). Paying attention to standards here makes raw materials and precursors expensive. But transparency in complying with and exceeding standards can make a decisive contribution to the better marketing of end products today.

Firecrackers and fireworks are a problem in every respect: for the animal world, the environment and the people who produce them. The ultrafine particles pollution is horrendous. And all this only because people (mostly men) hope for attention and admiration about this.

This does not refer to the skater track or the artificial turf sports field, but motorsport, skiing on artificially snowy slopes, kiting in bird protection areas, sailboats with biocides on the underwater ship, golfing with high use of water and pesticides, quad rides into nature, skydiving, etc. Of course, these hobbies are fun, which is why it is rewarded if we actively offer the more environmentally friendly alternatives here and thus achieve a rethink among our guests.
