Stuart, remember that the Rebbe studied physics at the Sorbonne.
Solar power can be used passively by designing houses with windows on the south side and use of deciduous trees that shade in Summer and allow sun in the Winter.
Photovoltaic is gettting less expensive with newer technology that doesn't use silicon wafers.
I also read that a solar plant heating water to steam for electric generators could be built in the zouthwest that could power most of California, Arizona and New Mexico.
Wind power is also actually solar power because wind is caused by differential heating of the air by the sun.
It is incumbant on us to try to do everything we can to rid our dependence on foreign oil because oil revenue funds those who would seek to destroy us.
The Rebbe z"l certainly had it right!

The development of technology to harness the abundance of energy provided by our sun in addition to other natural occurring phenomena (wind, geothermal, etc...) is essential to the future of all inhabitants of this planet. There are numerous examples in the Torah that provide us insight into the powers that He has provided us, and these lessons deal with the use or abuse of such power. The Rebbe illuminates this importance as he saw it at that time, under the weight of existing global pressures, this should serve both servants of the Creator or servants of creations with a dire responsibility, to heedlessly study His words as well as the words and works of those who walk in His path. May we be led toward the world to come, abundant in all things (tangible or spiritual) that He has so generously provided.

While the technology did not exist in 1981 nor is it practical today, with G-d's help we'll be there soon. There is new technology being developed everyday, even biological reactors.
I doubt there will be solar panels at 770 Eastern Parkway, where the sun's angle of incidence is not suited for this, but maybe at the Chabad Houses in Phoenix.
The Rebbe knew a great deal about science and governance, he should have been Secretary of Energy!
