A dereverberation and noise reduction method adapted for a microphone array and an apparatus using the same are proposed. The microphone array receives a plurality of audio signals from an audio source. The dereverberation and noise reduction method includes the following steps. The received audio signals are processed by a beamforming processing, and a first audio signal is generated.

Further, suppression audio vector is processed by an adaptive filtering processing, and a second audio signal is generated. In addition, the second audio signal is subtracted from the first audio signal to acquire an audio output signal, where parameters of the adaptive filtering processing are adjusted according to a feedback of the audio output signal.

A device is disclosed that uses short term solar energy forecasting to enhance the use of energy storage coupled to an electrical load. By predicting momentary fluctuations in solar energy output, the energy storage is controlled to avoid short term drops in energy production resulting in higher apparent electrical load and potentially higher demand charges. By enhancing the use of the energy storage, less storage is required to mitigate demand charges, thereby reducing capital costs.
