(including its subsidiaries, the “Company”) was organized as a Delaware corporation on April 25, 2000. The Company is a provider of energy efficiency solutions for facilities throughout North America and Europe. The Company provides solutions, both services and products, that enable customers to reduce their energy consumption, lower their operating and maintenance costs and realize environmental benefits. The Company’s comprehensive set of solutions includes upgrades to a facility’s energy infrastructure and the construction and operation of small-scale renewable energy plants. It also sells certain photovoltaic (“PV”) equipment worldwide. The Company operates in the United States, Canada, United Kingdom and Europe.</font><font style="font-family:inherit;font-size:1pt;"> </font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company is compensated through a variety of methods, including: 1) direct payments based on fee-for-services contracts (utilizing lump-sum or cost-plus pricing methodologies); 2) the sale of energy from the Company’s energy assets; and 3) direct payment for PV equipment and systems.</font></div></div>
CY2019	us-gaap	Use Of Estimates UseOfEstimates	<div style="font-family:Times New Roman;font-size:10pt;"><div style="line-height:120%;padding-bottom:8px;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;font-style:italic;font-weight:bold;">Use of Estimates</font><font style="font-family:inherit;font-size:10pt;"> </font></div><div style="line-height:120%;padding-bottom:6px;padding-top:6px;text-align:left;text-indent:18px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The most significant estimates and assumptions used in these consolidated financial statements relate to management’s estimates of final construction contract profit in accordance with accounting for long-term contracts, allowance for doubtful accounts, inventory reserves, realization of project development costs, leases, fair value of derivative financial instruments, accounting for business acquisitions, stock-based awards, impairment of goodwill and long-lived assets, asset retirement obligations (“AROs”), income taxes, self insurance reserves and potential liability in conjunction with certain commitments and contingencies. Actual results could differ from those estimates.</font></div><div style="line-height:120%;padding-bottom:8px;text-align:left;text-indent:24px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;">The Company is self-insured for employee health insurance. The maximum exposure in fiscal year </font><font style="font-family:inherit;font-size:10pt;">2019</font><font style="font-family:inherit;font-size:10pt;"> under the plan was </font><font style="font-family:inherit;font-size:10pt;">$150</font><font style="font-family:inherit;font-size:10pt;"> per covered participant, after which reinsurance takes effect. The liability for unpaid claims and associated expenses, including incurred but not reported claims, is determined by management and reflected in the Company’s consolidated balance sheets in accrued expenses and other current liabilities. The liability is calculated based on historical data, which considers both the frequency and settlement amount of claims. The Company’s estimated accrual for this liability could be different than its ultimate obligation if variables such as the frequency or amount of future claims differ significantly from management’s assumptions.</font><font style="font-family:inherit;font-size:1pt;"> </font></div></div>
