The indicating is clear to me. Having said that, I have seemed it up inside the dictionary and I have never identified any case in point sentence showing "to check for". Could it be suitable? Wouldn't "to check" just suffice?

They located that less than some of the eventualities they modeled, LAES check these guys out can be economically practical in specified places. Sensitivity analyses confirmed that policies giving a subsidy on capital expenditures could make LAES methods economically viable in several areas. Further calculations confirmed that the expense of storing a offered number of electricity with LAES would be lower than with additional acquainted programs for instance pumped hydro and lithium-ion batteries.

Through the two days, speakers emphasised that the Price tag-for each-unit and scalability of clean energy systems will ultimately ascertain their destiny.

Included: Personally, I agree with entangledbank above: entangledbank explained: For most senses there is basically no difference. Many people could possibly use a single or the opposite much more, or may possibly make a distinction, but there is no normal rule we can give. Click to grow...

Cetegen has adapted the product and is now calculating the NPV and LCOS for energy storage working with lithium-ion batteries. But click she’s currently inspired via the LCOS of liquid air storage. “Although LAES devices may not be economically feasible from an investment viewpoint currently, that doesn’t mean they gained’t be carried out Down the road,” she concludes.

The rain makes it a lot harder to possess a picnic, but we understand how to make the best of a bad scenario.
