A. either now or within a few years will be economically competitive with conventional sources of heat and power
This sentence separates subject from verb with awkward phrase of "either now or within a few years". Moreover it does not make any sense when we say "There is substantial evidence that certain forms of solar energy either now will be economically competitive with conventional sources of heat and power". How future will be can describe present activity.

B. will either be economically competitive with conventional sources of heat and power within a few years or are so now
Original sentence is saying either now or within a few years, this option reverses the order so incorrect.

C. will be economically competitive with conventional sources of heat and power either now or within a few years.
Use of "will be" for present situation is incorrect.

D. either are now economically competitive with conventional sources of heat and power or will be so within a few years
In this context "are" and "now" form redundant pair. We can safely ignore "now" and sentence will still make same sense. But this option is superior to other. Use of "so" in or section to correctly refer to verb in either construction is perfect.

E. are either now or will be within a few years economically competitive with conventional sources of heat and power
In this context "are" and "now" do not forms redundant pair, however as such will mean "are" is applied to both "either as well as or construction" which I will say is grammatically flawed. Moreover there is nothing in either construction that refers to verb of or construction.

I think redundancy is still allowable but grammatical mistakes are not, please correct me if I am wrong.

So I will go with D.

A. either now or within a few years will be economically competitive with conventional sources of heat and power
forms now economically competitive OR forms within few years will be economically competitive
We need 'are' in the first half.

B. will either be economically competitive with conventional sources of heat and power within a few years or are so now
forms will be economically competitive...OR forms will are so now
C. will be economically competitive with conventional sources of heat and power either now or within a few years
heat and power either now or within a few years..
(power either now ?)

D. either are now economically competitive with conventional sources of heat and power or will be so within a few years
...forms are now economically competitive..OR forms will be economically competetive
Sounds good..
E. are either now or will be within a few years economically competitive with conventional sources of heat and power
forms are now economically competitive OR forms are will be economically competitive
(are will ?)

I agree with the explanation provided. It should be D.

B. will either be economically competitive with conventional sources of heat and power within a few years or are so now

C. will be economically competitive with conventional sources of heat and power either now or within a few years

D. either are now economically competitive with conventional sources of heat and power or will be so within a few years

E. are either now or will be within a few years economically competitive with conventional sources of heat and power

Only D has the correct tense, and that's my pick...

In A, the sentence can be read as: "now will be"
In B, "will are so now"
In C, "will be ... now"
In E, "are will be"

This took me close to 2 min.
Too tough.

Boils down to C vs D.

evidence that energy "will be economically competitive with conventional sources of heat and power now" OR "will be economically competitive with conventional sources of heat and power within a few years"
The first fragment has a verb tense problem because "will be" is in the future tense.

D however treats both fragments correctly. "Are" in the first fragment and "will be" for the 2nd fragment.

So I choose D.

The sentence means to say that --- There is substantial evidence that certain forms of solar energy either now will be economically competitive or within a few years will be economically competitive with conventional sources of heat and power. You can see the incongruity of the theme --- now will be economically competitive. So any choice that has – now will be economically competitive can be eliminated

Second thing is the adherence to //ism of correlative conjunction.

A. either now or within a few years will be economically competitive with conventional sources of heat and power --- fouls on ---now and will be ---factor. drop

B. will either be economically competitive with conventional sources of heat and power within a few years or are so now --- be economically is not a full verb . So its placement after either is not correlatively // with or are so now. – drop.

C. will be economically competitive with conventional sources of heat and power either now or within a few years ---- fails on now and will be factor. ---drop

D. either are now economically competitive with conventional sources of heat and power or will be so within a few years …correct choice. –no now and will be problem and maintains correlative //ism

E. are either now or will be within a few years economically competitive with conventional sources of heat and power …… -are either now or will be within a few years - is not correlatively parallel.
