The impact of climate change on Europe's electricity demand
Science for Environmental Policy, December 2010
The impact of climate change on electricity consumption is important to both adaptation and mitigation policies. New research has estimated that over the next 100 years climate change could cause up to a 20 per cent decrease in demand for electricity for heating in Northern Europe and up to a 20 per cent increase in demand for electricity for cooling in Southern Europe.

China overtakes U.S. as biggest energy consumer
IEA calculations based on preliminary data show that China has now overtaken the United States to become the world's largest energy user. China's rise to the top ranking was faster than expected as it was much less affected by the global financial crisis than the United States. Read more...
U.N. Reports on Developing Nations’ Energy Needs
The New York Times, September 1, 2009
It will cost between $500 billion and $600 billion every year for the next 10 years to allow developing nations to grow using renewable energy resources, instead of relying on dirty fuels that worsen global warming, according to a United Nations report released Tuesday.
That astronomical estimate, far higher than any previously suggested by the United Nations, comes at a time when developed and developing nations are still deeply divided over who bears the responsibility for shouldering the expense of deploying cleaner energy resources, much less what the actual amount might be.

New renewables to power 40 per cent of global electricity demand by 2050
ENN, March 11, 2009
With global cooperation and investment, renewables’ share will exceed all previous estimates
With adequate financial and political support, renewable energy technologies like wind and photovoltaics could supply 40 percent of the world's electricity by 2050, according to findings from the International Scientific Congress "Climate Change: Global Risks, Challenges & Decisions." However, if such technologies are marginalized, its share is likely to hover below 15 percent. Read more...

Μιλάμε για πράσινη ενέργεια ή... πράσινα άλογα
Ελευθεροτυπία, 11 Ιανουαρίου 2009
Τη στιγμή που στην Αμερική και στην Ευρώπη οι κυβερνήσεις προσανατολίζονται σε μαζικές επενδύσεις σε μακροχρονίως βιώσιμες και φιλικές προς το περιβάλλον μορφές ενέργειας, η Ελλάδα συνεχίζει να βασίζει τον ενεργειακό σχεδιασμό και μάλιστα της ηλεκτροπαραγωγής της των επόμενων 40 ετών στα ορυκτά καύσιμα.

Βλάπτουν το περιβάλλον οι τηλεοράσεις plasma
TA NEA, 13 Ιανουαρίου 2009
Για τους Βρετανούς είναι «τα 4Χ4 του σαλονιού»: όπως τα τζιπ μεγάλου κυβισμού, έτσι και οι τεράστιες τηλεοράσεις plasma βαρύνονται ιδιαίτερα για τη μόλυνση του περιβάλλοντος. Γι΄ αυτόν τον λόγο, η κυβέρνηση Μπράουν στη Βρετανία σκοπεύει να απαγορεύσει τη διάθεσή τους στην αγορά. Διαβάστε περισσότερα...
Coal to remain world's top power source: IEA
ENN, November 14, 2008
LONDON (Reuters) - Coal, which produces more climate-warming carbon dioxide than oil or gas, will remain the world's main source of power until 2030 and nuclear will lose market share, the International Energy Agency said on Wednesday.
Expectations of slower economic growth have led the IEA to downgrade its 2030 world electricity demand forecast to 23,141 terawatt hours (TWh), but the share of coal generated power would rise to 44 percent by 2015 from 41 percent in 2006. It would stay at that level to 2030. Read more...

Daylight Saving Wastes Energy, Says Study
The Wall Street Energy, February 27, 2008
For decades, conventional wisdom has held that daylight-saving time, which begins March 9, reduces energy use. But a unique situation in Indiana provides evidence challenging that view: Springing forward may actually waste energy. Read more...
Οι στόχοι της Ε.Ε. για την ενέργεια
Καθημερινή, 22 Ιανουαρίου 2008
Η Ευρωπαϊκή Επιτροπή παρουσιάζει την Τετάρτη τα προσχέδια μιας σειράς νόμων για την ενεργειακή πολιτική των «27».
Γενικοί στόχοι
Μείωση 20% των εκπομπών των αερίων του θερμοκηπίου μέχρι το 2020, συγκριτικά με τα επίπεδα εκπομπών του 1990. Η μείωση ενδέχεται να αυξηθεί στο 30% εφόσον υπάρχει διεθνής συμφωνία επί του ζητήματος.
Το 20% της ενέργειας μέχρι το 2020 χρειάζεται να προέρχεται από ανανεώσιμες πηγές ενέργειας όπως η αιολική, η ηλιακή, η υδροηλεκτρική και η χρήση βιομάζας. Η συμμετοχή των ανανεώσιμων πηγών στη συνολική παραγωγή ενέργειας την τρέχουσα χρονική περίοδο, αντιστοιχεί στο 8,5%.
Τα καύσιμα των μέσων μαζικής μεταφοράς πρέπει να χρησιμοποιούν βιοκαύσιμα σε ποσοστό 10%. Διαβάστε περισσότερα...
67% Of Consumers Willing To Pay More For Green Power
Environmental Leader, December 13, 2007
Sixty-seven percent of consumers polled across six countries - Australia, Germany, Japan, the Netherlands, the United Kingdom and the United States - would be more willing to pay for eco-friendly energy, according to Plugging in the Consumer: Innovating utility business models for the future, a report from IBM Global Business Services that forecasts how changes in energy customers’ expectations will impact the utility industry’s business model in the next five to ten years..

Energy needs 'to grow inexorably'
BBC News, November 7, 2007 The global demand for energy is set to grow inexorably through to 2030 if governments do not change their policies, warns a top energy official.
Nobuo Tanaka, executive director of the International Energy Agency (IEA), said such a rise would threaten energy security and accelerate climate change. He said energy needs in 2030 could be more than 50% above current levels, with fossil fuels still dominant. Read more...
