What is the renewable energy source with the highest potential for electricity generation over the next few years?

I believe it will be photovoltaic cells.

I concur that photovoltaic will probably be the front runner.

According to a photo gallery, "Keeping Up with Renewable Energy: 5 Big Things You Might Have Missed," I read here on EC&M just today wind has overtaken solar: "#3: Wind tops nation in renewable energy capacity for the first time".

Hi there. I agree with photovoltaic cells.

Rich, I am on the training committee and have a question on Hornet electrical.

When the ship was active there were 4 sstg and 2 diesel generators. #2 main engine control has an active electrical panel servicing the ship. With 4 electric busses, my understanding was that underway #1 and #2 busses and #3 and #4 busses were parallel. At GQ all busses were separate.

Is the electric panel in engine room #2 the main electric control for the power from sstg and diesel? I ask because guests like to lean over the chain or try to cross to take pictures. My comment to them is that the panel is active and not an exhibit. Is shore power routed through the panel in engine room #2?

Thanks!

When the ship was underway at normal cruising, three ship service generators were on the line operating in parallel and all bus ties were closed.

At General Quarters all four generators were on the line operating split plant (all bus ties open).

Engine Room #2 has not been restored and is not open to the public. Engine Room #1 has #2 Main Switch Board (2S) and #2 Ship Service Generator (2SG) There are 4 Main Switch Boards and they are all energized. The two Emergency Generators (EGs) feed their own switch boards and have no feedback capability.

There are 2 shore power feeders. One is connected to 2S and the other is connected to 3S both through circuit breakers on the switch boards.

Thank you for clarification on shore power feed and bus tie. I will pass on the information. I was a flight engineer on 707 a/c and #2 Main Sw Bd. Reminds me of the 707 electrical panel.

More on Solar PV power. The April 2017 issue of Electrical Apparatus has an article stating the industry added more generating capacity than any other source of energy for the first time ever. Also, the cost for installing solar-powered systems has dropped by more than 60% over the last decade. To read the entire article ("Solar installations nearly doubled in 2016") see page 14, under Renewable Energy.
