The Energy Technology Data Exchange (ETDE), an IEA Implementing Agreement, is funded through its member countries' annual membership contributions. In addition, each member must cover the literature published in their country for inclusion in ETDE's Database. Because of this investment of resources, database access is controlled.
ETDEWEB is the latest product sponsored and financially supported by ETDE's members. Residents of member countries are eligible to use this product. According to the ETDE Implementing Agreement, each member has the right to set policies regarding access to ETDE products for their residents. Since each member does expend considerable resources to participate in ETDE and to provide the contents of ETDEWEB and other ETDE products, sometimes these products cannot be offered free of charge.
I seen the map available but could not Access because I was not registered. It said it was free.
I got this email from them. Thank you for registering. You will be contacted via email as soon as your account is approved.
You will not be able to log on to ETDEWEB until your account has been approved.
I will let you know how it works out.
