Accounting Policies [Abstract]
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill and Other Indefinite-Lived Intangible Assets The Company applies a fair value-based impairment test to the carrying value of goodwill and other indefinite-lived intangible assets on an annual basis (as of October 31) and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis. As disclosed in Note 2, "Significant Accounting Policies - Goodwill and Other Indefinite-Lived Intangible Assets," to the consolidated financial statements in Item 8 of its 2021 Annual Report on Form 10-K, the Company concluded there was no impairment in its goodwill and other indefinite-lived intangible assets as of October 31, 2021. During the three months ended September 30, 2022, the Company identified a triggering event for its clean energy reporting unit requiring an interim impairment assessment to be performed due to the loss of a key customer as well as certain clean energy product warranty-related matters. Estimates and assumptions used when preparing the discounted cash flow analysis for purposes of the interim impairment test were based on updated projections that are subject to various risks and uncertainties, including forecasted revenues, expenses, and cash flows as well as the current discount rate based on the estimated weighted average cost of capital for the business. Based on the interim impairment assessment as of September 30, 2022, the Company determined that the goodwill and indefinite-lived intangible assets ascribed to the clean energy reporting unit are not impaired. If management's estimates of future operating results change or if there are changes to other assumptions due to the economic environment, the estimate of the fair values may change significantly. Such change could result in impairment charges in future periods, which could have a significant impact on the Company's operating results and financial condition.

The Company applies a fair value-based impairment test to the carrying value of goodwill and other indefinite-lived intangible assets on an annual basis (as of October 31) and, if certain events or circumstances indicate that an impairment loss may have been incurred, on an interim basis.
