For years, grid parity – the time when solar and wind would be cost-competitive with fossil fuels and nuclear – was the holy grail of renewables energy, a target to reach in a distant future. But the future is now.
Renewables currently generate very little of Puerto Rico’s electricity but hopefully this could change after Hurricane Maria.
Tapping solar vast potential is one of our best bets to become carbon neutral by 2040. As prices keep on dropping, one of the remaining problems is the look of the panels themselves.
The agreement signed late last month may be the beginning of a new era of collaboration on climate change as the three North American countries signed an agreement to push cleantech and fight climate change.
Now this is … strange ? odd ? bizarre ? weird ? I was reporting in October that oil prices had dropped below $90, but last week they went even lower with as little as $50 a barrel. This is a 55% drop compared to last June.
It is almost common knowledge that solar panels should face South as it maximizes the amount of energy the panels can produce. However a study from Pecan Street Research Institute show some interest in pointing solar panels west. Solar panels facing in this direction produce more electricity when demand peaks, thus reducing the need for… Continue reading Should solar panels really face west ?
You must know if if you have been reading this blog : albeit it is not as ” sexy “ as renewables, energy efficiency is simply a must as we embark our societies and economies on a journey towards sustainability. Here is further proof as Cleantechnica notes : ” Energy efficiency retrofits (…) created a… Continue reading Energy efficiency brings huge returns on investment
To Enerdata ” global wind capacity increased by 12.5% in 2013, reaching 318,137 MW. During the year, 35,467 MW were installed worldwide, which is almost 10 GW below capacity additions in 2012. “ ” US installations were badly impacted by a policy gap created by the US Congress in 2012; in Europe, installations grew by… Continue reading Global wind capacity grew by 12.5 % in 2013
The energy transition from our model based on a huge majority of polluting fossil fuels to a model based on cleantech technologies such as energy efficiency and renewable energy sources will require a lot of money. Indeed, we have seen recently that up to a trillion dollar would be needed every year to do so.… Continue reading The energy transition already creates jobs
This was a major setback for me last week, US greenhouse gases emissions related to energy rose two percent in 2013 compared to 2012. To the US EIA this is due to ” a small increase in coal consumption in the electric power sector. “ ” Coal has regained some market share from natural gas since a… Continue reading Emissions in United States rebounded in 2013
According to new data from the US Energy Information Administration (EIA, how confusing…), the national energy-related carbon dioxide emissions declined by 3.8 percent last year, thus reaching their levels of 1994 while the economy grew. Many factors contributed to this drop in emissions. Among them are a warmer winter, a more efficient economy (notably new… Continue reading United States emissions decreased by 3.8 percent in 2012
I almost never watch news on TV as I find them too depressing and too little focused on the topics that matter to me. So I prefer scanning a few newspapers, my Netvibes page and its many RSS feeds, and, of course, Twitter. But my dear mom still watches the news and thus came across… Continue reading The VolturnUS, a US floating wind turbine
