High metal prices can drive up the costs of electric car batteries, which will reduce their adoption. Car manufacturers are already responding to this by shifting to different technologies.
Covering less than ten per cent of the world’s hydropower reservoirs with floating solar panels would yield as much energy as all hydropower does today, one researcher says.
Even though new hydropower dam developments are intended to provide green energy, they can drown areas that are rich in plant and animal species. But this kind of collateral damage can be limited by strategic site selection, a new study shows.
The 1969 discovery of oil at the Ekofisk field in the North Sea transformed Norway into an internationally important energy nation. But long before black gold was being pumped from the Norwegian Continental Shelf, Norway’s economy was fuelled by a different kind of energy: hydropower.
Production of electricity is responsible for about a quarter of global greenhouse gas emissions, and demand is poised to rise as underserved populations connect to the grid, and electronics and electric vehicles proliferate. So stopping global warming will require a transformation of electricity production. But it is important to avoid various environmental pitfalls in this transition, researchers say.
An international team of researchers has concluded that operational funding should continue to be provided for the production of renewable energy in Europe, provided that such support is progressively reduced over time.
The transition to green energy hasn’t really begun, according to Associate Professor Espen Moe. Even though the 278 new wind turbines that will be built in central Norway are an important investment, it’s not nearly enough, he says.

Privacy Policy
The Privacy Statement is about how this website collects and uses visitor information. The statement contains information that you are entitled to when collecting information from our website, and general information about how we treat personal data.The legal owner of the website is the processing officer for the processing of personal data.

The treatment basis is the consent of the individual, unless otherwise specified.
1. Web analytics and cookies (cookies)
As an important part of the effort to create a user-friendly website, we look at the user pattern of those who visit the site. To analyze the information, we use the Google Analytics analysis tool.Google Analytics uses cookies (small text files that the site stores on the user's computer), which registers the users' IP address and provides information about the individual user's online movements. Examples of what the statistics give us answers to are; how many people visit different pages, how long the visit lasts, what websites users come from and what browsers are used. None of the cookies allow us to link information about your use of the site to you as an individual.The information collected by Google Analytics is stored on Google servers in the U.S.. The information received is subject to the Google Privacy Policy.An IP address is defined as a personal information because it can be traced back to a particular hardware and thus to an individual. We use Google Analytics's tracking code to anonymize the IP address before the information is stored and processed by Google. Thus, the stored IP address can not be used to identify the individual user.
2. Search
If the webpage has search function, it stores information about what keywords users use in Google Analytics. The purpose of the storage is to improve our information service. The search usage pattern is stored in aggregate form. Only the keyword is saved and they can not be linked to other information about the users, such as the IP addresses.
3. Share / Tips service
The "Share with others" feature can be used to forward links to the site by email, or to share the content of social networking. Tips for tips are not logged with us, but only used to add the tips to the community. However, we can not guarantee that the online community does not log this information. All such services should therefore be used wisely. If you use the email feature, we only use the provided email addresses to resend the message without any form of storage.
4. Newsletter
The website can send out newsletters by email if you have registered to receive this. In order for us to be able to send e-mail, you must register an e-mail address. Mailchimp is the data processor for the newsletter. The e-mail address is stored in a separate database, not shared with others and deleted when you unsubscribe. The e-mail address will also be deleted if we receive feedback that it is not active.
5. Registration, form
The website may have a form for registration, contact form or other form. These forms are available to the public to perform the tasks they are supposed to do.Registration form is for visitors to sign up or register.Contact form is for visitors to easily send a message to the website's contact person.We ask for the name of the sender and contact information for this. Personal information we receive is not used for purposes other than responding to the inquiry.The form is sent as email via Mailgun as a third party solution. The entire submission will be stored at Mailgun for 24 hours. Between 24 hours and 30 days, only mailheader is stored before the submission is deleted after 30 days. The reason for this storage is to confirm whether emails are sent from the website and forwarded to the correct recipient.Once the email is received by the recipient, it is up to the recipient to determine the data processing needs of the email.
