Intents and Broadcast Receivers Challenge Task Error

The questions says: Now we need to retrieve the new extra in TimeTravelActivity. Add an EnergySource variable and set it to the extra from the Intent. The error I'm getting is this:

./TimeTravelActivity.java:15: error: incompatible types: Parcelable cannot be converted to EnergySource
    EnergySource source = intent.getParcelableExtra("EXTRA_ENERGY");
                                                   ^
1 error

The previous question clearly says that the EnergySource implements the Parcelable interface. If that was true, then why I'm getting this error?

MainActivity.java 
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {

  public Button goButton;
  public EditText yearField;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    goButton = (Button)findViewById(R.id.goButton);
    yearField = (EditText)findViewById(R.id.yearField);

    final EnergySource source = new EnergySource();

    goButton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        // Add your code in here!
        Intent intent = new Intent(MainActivity.this, TimeTravelActivity.class);
        intent.putExtra("EXTRA_YEAR", yearField.getText().toString());
        intent.putExtra("EXTRA_ENERGY", source);
        startActivity(intent);
      }
    });
  }
}
TimeTravelActivity.java 
import android.os.Bundle;
import android.view.View;

public class TimeTravelActivity extends Activity {

  public String targetYear;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_time_travel);

    Intent intent = getIntent();
    targetYear = intent.getStringExtra("EXTRA_YEAR");
    EnergySource source = intent.getParcelableExtra("EXTRA_ENERGY");
  }
}

dont forget to type cast EnergySource source=(EnergySource)intent.getParcelableExtra("EXTRA_ENERGY");
