Alternative Energy and Climate Change

I know very little about the very little and even less about the very large. A lifetime of study and experience has yielded a pretty good feel for transport phenomena, thermodynamics, scaling...

If the Earths climate is driven by differential solar heating and the resultant fluid streams, then modification of those fluid streams will modify climates. Hydroelectric dams, gulf stream turbines, and windmills sufficient to displace current energy conversion means will modify climates. The Gulf Stream that warms Europe is a long period bistable oscillator and its switching is associated with the creation of a positive feedback loop that precipitates ice ages and the slowing of this stream by turbogenerators may have just such consequence.  

We must be willing to question whether alternative energy schemes should be above criticism and if we are willing or capable of making  honest appraisals of our visions?

Comment on a social media share:

You are right to be cautious but be very careful in your selection of data; when considering systems, it is very easy to draw an artificial boundary around the data you are interested in, ignoring critical data that is outside the boundary you create. Yes extracting energy from the Gulf stream might cause a problem if the energy extracted is large enough; however, the pollution in the atmosphere is likely to be reduced, if the energy generated replaces the equivalent amount of fossil currently being burnt! It is important that we have a good computerised model before we go in for "geo-engineering" type projects; so caution is the byword but do not through the baby out with the bathwater!

Another social media share comment:
"Wow! What a question to propose. I am not an expert at all so my input is purely based on personal opinion. My opinion is yes we do need to question these renewable systems in their possible disruptive forms to the surrounding climate but not by anyone other then the specialist in these areas. Their trained knowledge with data is the only way you will stop the climate deniers, the coal mungers and the standard layman from thinking they have a real, rational conversation to this. The expert driven results can then be shown to the rest of us in a concise understandable report. Of course there will always be the statement that results and reports are driven by big business profits but who has ever had that control to keep it above board. Even governments can influence to suit political agendas. That's my 2cents worth!"

Rachael Lewis. how is thinking in climate Change, is need assist from human to cooperation solution in dams. is huge Impacts. so The importance in creating ideas from the dams, the system to store and operate water resources in the place in dams, more important for the environment, is more developed than the construction to the provision on water solutions for the environment and the solution, to generate electricity power from dams.

The comment is not my own Ali, it is from another who saw the post on social media.

The Energy Central Power Industry Network is based on one core idea - power industry professionals helping each other and advancing the industry by sharing and learning from each other.

If you have an experience or insight to share or have learned something from a conference or seminar, your peers and colleagues on Energy Central want to hear about it. It's also easy to share a link to an article you've liked or an industry resource that you think would be helpful.
